Optical and gamma-ray shielding properties of calcium sodium borate glasses with varied equal concentrations of ZnO and BaO

This study presents the optical and radiation shielding characteristics of a newly developed borate glass, doped with equal quantities of ZnO and BaO, and modified with calcium and sodium. The glass samples were prepared using the melt quenching technique, with the composition formula (80-x-y)B2O3-10CaO-10Na2O-xZnO-yBaO, where x and y were varied at 5, 10, 15, and 20 mol%. Comprehensive analyses of the optical and gamma shielding properties were carried out using UV–visible spectrophotometry and Phy-X software, respectively. The UV–visible spectroscopic data allowed for the calculation of various parameters including the direct and indirect optical energy band gaps, refractive index, dielectric constants, and polarizability. It was observed that the direct optical energy band gap decreased from 3.91 to 3.10 eV, while the indirect band gap fell from 3.41 to 2.91 eV with increasing ZnO and BaO content. Conversely, the refractive index rose from 2.29 to 2.42 with higher concentrations of ZnO and BaO. The linear attenuation coefficients (LACs) across the range of 0.015–15 MeV exhibited an inverse relationship. Among the glass samples, B40Zn20Ba20 exhibited the lowest tenth value layer (TVL) and the highest effective atomic number (Zeff), indicating its superior performance as a radiation shielding material. Overall, the produced glass samples demonstrate commendable properties for both optical applications and radiation shielding.

Tailoring optimal KERMA, projected range, and mass stopping power, and gamma-ray shielding capabilities through BaO/ZnO/CdO/SrO incorporation into Na2O–SiO2 glasses

This study explores the radiation shielding potential of Na2O–SiO2 glass matrices doped with BaO, ZnO, CdO, and SrO, analysed across a broad energy spectrum. The research employed various computational tools such as Phy-X/PSD and PAGEX codes to calculate various shielding parameters, including Kinetic Energy Released in Material (KERMA), mass stopping power, fast neutron, and gamma-ray attenuation properties. Among the glass samples, S3, with its BaO content, exhibited the most advantageous properties in terms of radiation attenuation. The results showed that S3 has the lowest Half Value Layer (HVL) of 0.032 cm at 0.015 MeV and the highest KERMA value, peaking at 0.3 MeV with 0.18 MeV/g. The mass stopping power values for alpha particles in the S3 sample showed a pronounced peak at 0.7 MeV, reaching 150 MeV cm2/g, indicating superior energy absorption. The S3 sample, composed of 20% Na2O, 20% BaO, and 60% SiO2, demonstrated the highest density (i.e., 3.225 g/cm³) and effective atomic number (i.e., 17.5), which contributed to its superior shielding performance. The study's findings show that the careful manipulation of glass composition, particularly through the incorporation of high-atomic-number oxides, can significantly enhance shielding effectiveness. It can be concluded that the S3 glass sample would be an optimal configuration for practical applications in radiation protection, where the Na2O–SiO2 glass matrices doped with BaO in terms of optimal material properties.

Impact of barium oxide on the structure and surface properties of glass-crystalline glazes

The influence of barium oxide on glazes in the SiO2-Al2O3-CaO-MgO-K2O system was investigated. Samples were prepared with 0, 2.5, 5 and 7.5 wt% of barium oxide added to this system. The glazes were fired at 1240 °C and the structure and surface properties were determined. Qualitative and quantitative analyses of phase composition, surface properties, structural mid-infrared analysis, and microstructure were performed.Diopside was detected in all glazes as the MgO content was higher than 2.5 wt%. Hyalophane crystals were observed when the BaO content increased to 5 wt%. Mid-infrared studies showed that the appearance of crystalline phases ordered the structure of the glazes; on the other hand, the amorphous phase increased its disorder related to the higher amount of modifying barium cations. The addition of barium oxide did not significantly affect the color of the surface but caused an increase in roughness due to surface crystallization. The microhardness increased with an increased amount of barium in the amorphous phase.

Mixed former effect in barium borophosphate glasses on the red (Eu3+)-blue (Eu2+) emission for LEDs

The synergistic mixing of P2O5 and B2O3 glass formers at a constant concentration of BaO as a glass modifier plays a vital role in generating a single-phase phosphor doped with Eu2O3 for white light-emitting diodes (WLEDs). Herein, a glass system of nominal composition xP2O5∙(50-x)B2O3∙49.5BaO∙0.5Eu2O3 (0 ≤ x ≤ 50 mol%) was prepared using a melt-quenching technique under normal atmospheric conditions. While the XRD patterns demonstrated the amorphous nature, the SEM micrographs proved the formation of cluster structures. Structural characterization using ATR-FTIR spectroscopy revealed the presence of main vibrational structural units associated with borate and phosphate glass formers, including BO3, BO4−, P=O, PO2−, and PO32−. The IR spectra at x = 0 and 50 mol% exhibit characteristic metaborate and metaphosphate absorption peaks, respectively. In contrast, the mixing of both B2O3 and P2O5 at equal concentrations (x = 25 mol%) has resulted in the absence of absorption peaks assigned to the BO3 and P=O units, thus indicating the mixed structural effect. This is assigned to the formation of B-O-P bonds, with the BO4−, PO2−, and PO32− as the main structural units. These structural changes affect the reduction process of Eu3+ to Eu2+, as demonstrated by the corresponding photoluminescence spectra and observed by the cathodoluminescence micrographs. Photoluminescence studies showed tunable emission from red (Eu3+) to white light (Eu2+ and Eu3+) under UV excitation, with the P2O5 content rising from 0 to 50 mol% due to the growing Eu2+ population formed by the reduction of Eu3+. The optical basicity was observed to decrease with the P2O5 content, favouring the reduction process. The demonstrated tunable single-host white phosphor makes this an attractive system for energy-efficient WLED applications.

Radiation Shielding Analysis of Multi-Component Glasses: Effects of Varying BaO, PbO2 and Gd2O3 Concentrations

This work investigates the impact of BaO, PbO2, and Gd2O3 on newly developed borate glasses’ radiation shielding characteristics. The transmission factor (TF) of the glasses is almost zero at the low energy of 0.0395 MeV, which indicates favorable low-energy photon shielding. The maximum TF is reported at 1.46 MeV for the free Gd2O3 glass sample, ranging from 0.89 (0.5 cm thickness) to 0.73 (1.5 cm thickness). Moreover, with more BaO, PbO2, and Gd2O3 content added to the glasses, the TF decreases, indicating an enhancement in the efficiency of the glasses’ radiation protection with the introduction of BaO, PbO2, and Gd2O3. There is a 4.309 to 5.068 g cm−3 increase in the glasses’ density, and, as a result, the mean free path decreases, suggesting improved performance for radiation protection with the adding of more BaO, PbO2, and Gd2O3 contents to the glasses. At 0.122 MeV, the free Gd2O3 glass’s half value layer value is 0.098 cm, while the tenth value layer is 0.325 cm.

Photon and thermal neutron shielding behaviors of aluminum calcium fluoroborate glass modified with barium oxide: FLUKA Monte Carlo, XCOM and experimental investigations

The borate glass system was prepared using the melt-quenching method. The XRD was used to confirm the amorphous structure of present samples, the FTIR was utilized to observe vibration modes, and the UV–Vis-NIR spectrophotometer was employed to measure transmittance spectra. The radiation shielding properties were examined by FLUKA Monte Carlo simulation, XCOM programs, and experimental methods. The density increased, while the molar volume decreased as the BaO content increased. For the X-ray and gamma-ray radiation, indicate that the addition of BaO instead of B2O3 improve the shielding properties, while the Σ is decreased for thermal neutron radiation. According to the results, adding BaO enhanced the X-ray and gamma-ray shielding properties. However, adding BaO led to the reduces its ability of shielding the thermal neutrons of the glass samples. These data are expected to be accommodate to considering for any applications which requires high efficiency of photon or thermal neutrons shielding.

Barium-bearing micas of the muscovite-ganterite series from alkaline rocks of the Sredneziminsky ijolite-syenite-carbonaite massif (Eastern Siberia, Russia)

Barium-bearing micas (BaO content from 1.2 to 18.7 wt %) were found in hydrothermally altered ijolites and alkaline syenite of the Sredneziminsky ijolite-syenite-carbonatite massif (Eastern Siberia, Russia). It occurs in the products of low-temperature replacement of cancrinite, in association with natrolite, analcime, calcite, diaspore/boehmite, celsian, and strontianite. Ba-bearing micas are represented by grains up to 1 mm, heterogeneous in chemical composition. The amount of Ba increases in the marginal parts of grains; enrichment of some layers in mica grains with barium is also observed. The main isomorphic substitution in muscovite corresponds to the scheme K++Si4+↔Ba2++IVAl3+. The empirical formula of barium-richest areas in one of the mica grains is (Ba0.54–0.56Sr0–0.09K0.46)∑1.02–1.06Al1.98–2.01(Si2.37–2.40All.60–1.63)∑4.00 O10(OH1.70–2.00F0–0.30)∑2.00, which corresponds to ganterite. The maximum content of BaO in the majority of muscovite grains of the Sredneziminsky massif is 14.0–14.9 wt % that is equal to 0.41‒0.44 apfu Ba. It is assumed that the source of barium in the hydrothermal solution was orthoclase containing 0.5–0.9 wt % BaO which underwent albitization at the post-magmatic stage. The widespread occurrence of sulfides in the rocks indicates low oxygen fugacity, which prevents the formation of barite and is favorable to the formation of Ba-bearing muscovite and celsian.

Effect of BaO addition on core-shell structure and electric properties of BaTiO3-based dielectrics for high-end MLCCs

Core-shell structured fine grain dielectrics, featured with high dielectric constant and wide temperature stability, are essential for the production of high-end MLCCs. In this work, the core-shell structured 100BaTiO3-xBaO-2.4MgO-1.0ZrO2-0.03MoO3-2.25Y2O3-0.3MnO2-2.0SiO2 (x = 0.5, 1.0, 1.5, 2.0, 3.0, 4.0) ceramics were prepared and the effects of BaO additions on the microstructure and dielectric properties were studied. The resulting ceramics exhibited fine grains (average size 280–300 nm) and demonstrated a high dielectric constant (>1780). Notably, the core-shell structure of the ceramics was affected by the BaO content, with the core volume gradually increasing as the BaO addition grew. This adjustment in composition was found to enhance the temperature stability and reliability of the materials. When the BaO addition reaches 4.0 mol%, the values of ΔC150/C25 °C were effectively suppressed from −22 % to −10.3 % to meet the X8R specification, and the insulation resistivity increased by more than an order of magnitude, reaching a maximum of 11.6 × 1012 Ω m. Our findings highlight the potential of BaO as an effective additive for enhancing the dielectric properties of core-shell structured fine grain dielectrics for high-end MLCCs.

BaO-doped Na2O–CaO–P2O5 bioactive glasses: A closer look at radiation attenuation properties for medical applications

This study investigates the nuclear radiation attenuation characteristics of bioactive glasses with the system (26-x)Na2O-xBaO-29CaO–45P2O5, where x represents the molar percentage of BaO (0, 5, 10, 15). For this purpose, several parameters of shielding gamma radiation, such as the mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), effective atomic number (Zeff), effective electron density (Neff), atomic cross-section (ACS), electronic cross-section (ECS), equivalent atomic number (Zeq), and transmission factor (TF) were calculated. The calculations were performed across different photon energy ranges (0.015–15 MeV) using Phy-X/PSD software and validated using the WinXCOM program. The results obtained from both the software platforms exhibited a high degree of agreement. Among the investigated glasses, the BNCP-15 glass, which had the highest BaO concentration, demonstrated the highest values for MAC, LAC, Zeff, Neff, ACS, ECS, and Zeq, while displaying the minimum values for HVL, TVL, MFP, and TF. For example, the LAC values at 15 MeV were found to be 0.056, 0.063, 0.070, and 0.077/cm for BNCP-0, BNCP-5, BNCP-10, and BNCP-15, respectively. Consequently, the BNCP-15 glass exhibited superior radiation attenuation performance in comparison to the other BNCP glasses examined in this study.

Enhancing bioactivity, radiopacity, and structural properties of borophosphate glass through barium oxide modification and controlled thermal treatment

This study explores the impact of replacing P2O5 and B2O3 with varying amounts of barium oxide (BaO, 0–10 mol%) in borophosphate glasses. The investigation focuses on the structural, bioactivity, and radiopaque properties of the resulting materials. Four glass samples were prepared using a melt-quench technique. Their bioactivity was assessed through immersion in simulated body fluid (SBF) for 28 days. Additionally, a 24-h thermal treatment at 530 °C was employed to induce crystallization and evaluate the bioactivity of the resulting glass-ceramics. Initial X-ray diffraction (XRD) analysis confirmed the amorphous nature of the glasses. Conversely, crystalline phases were identified after the thermal treatment. Increasing BaO content led to higher volumetric density while altering the molar volume and structure as revealed by Fourier-transform infrared spectroscopy (FTIR) analysis. Lower pH values were observed with increasing BaO content, suggesting its influence on controlling the release of ions from the material. Both XRD and FTIR analyses detected the formation of hydroxyapatite (HAp) and fluorapatite (FAp) phases in all samples. Notably, the glass-ceramic containing 10 mol% BaO exhibited the most significant apatite formation. Radiopacity measurements improved with increasing BaO content, indicating potential applications in bone replacement materials due to enhanced visibility in X-ray imaging. Cell viability tests confirmed the non-toxic nature of the samples, with higher BaO content promoting cell proliferation, suggesting potential for tissue regeneration. Overall, these findings suggest promising biomedical applications for all the studied compositions.

The hazardous protective glass material for gamma, neutrons, and behaviors of charged particles: Results of adding barium oxide concentrations

The objective of this research is to examine the effectiveness of gamma and neutron shielding, as well as to investigate the behavior of charged particles in glass compositions with the formula xBaO:5SnO2:10Na2O:10CaO:10Li2O: (65-x)SiO2. These glass compositions will be created using the melt quenching technique (MQT). The findings indicated that the physical characteristics, such as density and molar volume, exhibited a comparable pattern. The gamma-ray shielding capacity of the glass system was assessed by comparing it with theoretical, simulation, and experimental values obtained using WinXCom, PHITS (Particle and Heavy Ion Transport Code System) Monte Carlo simulation, and Compton scattering technique (CST), respectively. The results revealed that the total attenuation (μm), effective atomic number (Zeff), and electron density (Nel) exhibited a consistent increase with higher BaO contents. Additionally, this increase led to a decrease in scattering energy within the Compton energy range. The half-value layer (HVL) exhibited superior shielding characteristics compared to alternative substances. Furthermore, the addition of more BaO atoms in the glass structure results in an increased ability of the material to stop the motion of charged particles with larger mass. Conversely, lower concentrations of BaO demonstrate an efficient barrier against fast neutrons. The simulation revealed that BaO can be utilized as an additive in glass materials to enhance their radiation shielding properties in environments with high levels of radiation.

Structural Interaction between BaO and Al2O3 in Aluminosilicate Slags

The effect of BaO and Al2O3 on the viscosity of SiO2–CaO–MgO–Al2O3–BaO slag from 1673 to 1873 K is studied by the rotating cylinder method. The structure of slag is examined by Raman spectroscopy and molecular dynamics simulation. In this study of viscosity, Al2O3 shows amphoteric oxide characteristics and BaO shows characteristics different from the basic oxide. The viscosity increases as the BaO increases from 2 to 4 wt% in the slag with CaO/SiO2 = 1.07. However, the viscosity decreases when the BaO content increases from 6 to 8 wt%. From molecular dynamics simulations and Raman analysis, the increase in BaO content leads to a greater aggregation of Al around Ba atoms and increases the number of Al–O bonds. This indicates that higher BaO content promotes the polymerization of the [AlO4] tetrahedral structure. Furthermore, a good quantitative relationship between viscosity and the ratio of Q3/Q2 of the Raman spectrum of the slag is observed.

Effect of different BaO contents on the photoluminescence properties of the Eu2+-doped high thermal stability Sr3−xBaxMgSi2O8 phosphors

In this study, 0.015 Eu[Formula: see text]-doped Sr[Formula: see text]BaxMgSi2O8 ([Formula: see text], 0.3, 0.6, 0.9) were used as compositions to find the effect of BaO content on their photoluminescence excitation (PLE) and photoluminescence emission (PL) properties. They were sintered at 1400°C in a reduction atmosphere of 95% N[Formula: see text]% H2 to form blue phosphors. X-ray diffraction pattern and SEM observation were used to analyze their crystal properties, and a fluorescence spectrophotometer was used to analyze their PLE and PL properties. After conducting a thorough analysis, our research primarily encompasses four significant research themes. First, SEM observations revealed that synthesized Eu[Formula: see text]-doped Sr[Formula: see text]BaxMgSi2O8 phosphors exhibit the formation of whisker-like structures. Therefore, the whisker-like structures in all the Eu[Formula: see text]-doped Sr[Formula: see text]BaxMgSi2O8 phosphors were analyzed using the HRTEM and its equipped EDS to find how BaO content influenced both the quantity and fineness of these whiskers. Second, we examined the impact of BaO content on the PLE and PL emission intensities of the Eu[Formula: see text]-doped Sr[Formula: see text]BaxMgSi2O8 phosphors across a temperature range from room temperature to 210°C. This investigation aimed to uncover the effects of BaO content and temperature on the thermal stability of the Eu[Formula: see text]-doped Sr[Formula: see text]BaxMgSi2O8 phosphors. Lastly, our fourth important investigation involved reorganizing the PLE spectra of the Eu[Formula: see text]-doped Sr[Formula: see text]BaxMgSi2O8 phosphors with the energy band as the x-axis. The Gaussian fitting function was applied to analyze the excitation spectra and discern the influence of BaO content on the value of the Stokes shift.

The investigation of physical, optical, X/gamma-rays and thermal neutron shielding properties using experimental, simulation, and theoretical for BaO-based glass system

The optical, physical, X/gamma-rays, and thermal neutron shielding properties of the glass systems in formula xBaO: 10Na2O: 20ZnO: (70-x)B2O3 (x = 0, 10, 20, 30, 40, and 50 mol%) were examined. The glass systems were manufactured using the melt-quenching method. As the concentration of BaO in these glass samples increased, so did increase their densities and refractive indices. The BaO behaves differently on these glass structures depending on their composition, according to the molar volumes. The Ba2+ functions as a network modifier for compositions between 20 and 50 mol% of BaO, whereas it is incorporated as a network former for compositions less than 20 mol%. The X and gamma-rays shielding properties, the mass attenuation coefficients, half value layer, and the mean free path were compared between the experiment, FLUKA, and XCOM. Additionally, X and gamma-rays shielding characteristics were compared with those of certain standard materials. It was found that the increasing BaO concentration improved X and gamma-rays shielding properties. Moreover, the thermal neutron was also discussed on shielding properties.

An experimental and theoretical study to evaluate Al2O3–PbO–B2O3–SiO2–BaO radiation shielding properties

This study's objective is to evaluate an Al2O3–PbO–B2O3–SiO2–BaO glass system's radiation shielding characteristics. The composition of the glasses is 15Al2O3–25PbO–(60-x)B2O3–10SiO2–xBaO, with x in the 5–20 mol% range. Experimental results were used to determine the samples' linear attenuation coefficients (LAC), which were then confirmed by Phy-X program. Utilizing narrow beam transmission geometry, the experimental LAC values were determined. According to the results there was high agreement when comparing the theoretical and experimental values. The LAC values were used to calculate the prepared glasses' mass attenuation coefficients (MAC) and other relevant properties. The mean free path (MFP) values of the sample with 5 mol% BaO were 0.079, 2.549, 3.944 and 4.273 cm at 0.0595, 0.662, 1.173, and 1.332 MeV, thus demonstrating that raising the glass system's BaO enhances the prepared glasses' shielding capacity. According to radiation protection efficiency (RPE), the glasses' capacity to shield the photon is enhanced when their BaO content rises.

From structure to luminescence investigation of B2O3-GeO2-BaO-ZnO glass doped with Dy3+

This study describes the preparation of Dy3+ doped B2O3-GeO2-BaO-ZnO (BGBZ) glass using a high temperature melting technique. By means of excitation and emission spectroscopy, it was determined that the glass sample with 25 mol% BaO content had the maximum luminous intensity. The internal structure of the glass was investigated using FT-IR spectroscopy, absorption spectrum testing, and J-O theoretical analysis in order to investigate the principle. The FT-IR spectrum revealed the coexistence of [BO3], [BO4], [GeO4], and [GeO6] coordination polyhedra. The Ω2 value reaching its maximum when the BaO content reached 25mol%, indicating the highest degree of asymmetry in the glass structure at that time. After analyzing the impact of BaO content on the glass structure, it was investigated how the concentration of Dy2O3 doping affected the glass's optical characteristics and radiation performance. By calculating the CIE of glass samples, it was found that the CCT value of glass sample 1.25Dy was 6735 K, suggesting that the produced glass may find use in the w-LED commercial industry. The 0.50Dy glass sample was calculated to have a high σse (8.47×10−22 cm2) from the emission spectral data, suggesting that the prepared glass sample may also be suitable for lasers.

Impact of BaO Content on Gamma Radiation Shielding Attributes of Borosilicate Glasses at Low Energy Range

Impact of BaO Content on Gamma Radiation Shielding Attributes of Borosilicate Glasses at Low Energy Range

Experimental examination on physical and radiation shielding features of boro-silicate glasses doped with varying amounts of BaO

Investigations were conducted on the addition of barium's impact on the radiation shielding and physical attributes of five different glasses, designated S1–S5, with varying BaO contents. Using two point sources namely Co60 and Cs137 along with a scintillation detector [NaI(TL)], experimental measurements were made of the shielding parameters of γ-rays, namely the effective atomic number (Zeff), electron density (Nel), half-value layer (HVL), linear attenuation coefficient (μ), mass attenuation coefficient (μm), mean free path (λ), and radiation protection effectiveness at the energies of 0.664, 1.177, and 1.334 MeV, and comparisons made with recently considered glasses as well as frequently employed materials for γ-ray shielding. The results show that the examined glasses' physical and radiation shielding qualities are improved by the addition of BaO. The μ values increased from 0.245 to 0.275 cm−1 (0.662 MeV), from 0.174 to 0.198 cm−1 (1.173 MeV), and from 0.161 to 0.189 (1.332 MeV). The observed values of HVL decreased from 2.83, 3.98, and 4.3 cm to 2.5, 3.5, and 3.62 cm at 0.662, 1.173, and 1.332 MeV, respectively, for the samples S1 and S5. In addition, the S5 glass sample was determined to have the best protection against photon among all the samples that were evaluated, as well as against recently considered glasses and those materials often utilized for gamma-ray shielding purposes.

An extensive assessment of the impacts of BaO on the mechanical and gamma-ray attenuation properties of lead borosilicate glass

The current work deals with the synthesis of a new glass series with a chemical formula of 5Al2O3–25PbO–10SiO2–(60-x) B2O3–xBaO; x was represented as 5, 10, 15, and 20 mol%. The FT-IR spectroscopy was used to present the structural modification by rising the BaO concentration within the synthesized glasses. Furthermore, the impacts of BaO substitution for B2O3 on the fabricated borosilicate glasses were investigated using the Makishima-Mackenzie model. Besides, the role of BaO in enhancing the gamma-ray shielding properties of the fabricated boro-silicate glasses was examined utilizing the Monte Carlo simulation. The mechanical properties evaluation depicts a reduction in the mechanical moduli (Young, bulk, shear, and longitudinal) by the rising of the Ba/B ratio in the fabricated glasses. Simultaneously, the micro-hardness boro-silicate glasses was reduced from 4.49 to 4.12 GPa by increasing the Ba2+/B3+ ratio from 0.58 to 3.18, respectively. In contrast, the increase in the Ba/B ratio increases the linear attenuation coefficient, where it is enhanced between 0.409 and 0.448 cm−1 by rising the Ba2+/B3+ ratio from 0.58 to 3.18, respectively. The enhancement in linear attenuation coefficient decreases the half-value thickness from 1.69 to 1.55 cm and the equivalent thickness of lead is also reduced from 3.04 to 2.78 cm, at a gamma-ray energy of 0.662 MeV. The study shows that the increase in the Ba2+/B3+ ratio enhances the radiation shielding capacity of the fabricated glasses however, it slightly degrades the mechanical properties of the fabricated glasses. Therefore, glasses with high ratios of Ba2+/B3+ have high gamma-ray shielding ability to be used in hospitals as a shielding material.

Influence of barium substitution on the physical, thermal, optical and luminescence properties of Sm3+-doped metaphosphate glasses for reddish orange light applications.

Our present study focuses on examining the thermal, structural and luminescent characteristics of sodium barium metaphosphate glasses doped with Sm3+. Glass samples with molar compositions (100 - y)[(50P2O5)-(50-xNa2O)-(xBaO)]-ySm2O3, where x = 20, 25, 30, 35, 40 and y = 0.3 and 1% were first synthesized by conventional melt quenching and later dehydroxylated under a constant N2 flow to ensure final glasses with a very high degree of chemical and optical homogeneity and free of water. Upon the addition of BaO and Sm2O3, refractive index, molar mass, density, glass transition temperature and dilatometric softening temperature exhibited an increase, whereas the coefficient of thermal expansion showed a decrease. The FTIR spectra analysis reveals a network depolymerization that intensifies with rising BaO concentration, ultimately transitioning from a modifier oxide to a glass-forming element, at higher BaO concentrations. All doped samples exhibited prominent absorption bands in the visible (VIS) and near-infrared (NIR) regions, as revealed by the optical absorption spectra. The Na2O modifier demonstrated greater influence on Sm3+ emission compared to BaO, a phenomenon that can explained by the moderation of the local ligand field strength resulting from this substitution. With an increase in Sm2O3 concentration from 0.3 to 1 mol%, the experimental lifetimes of the 4G5/2 level decrease, primarily attributed to the presence of energy transfer mechanisms. A discussion of Judd-Ofelt parameter analysis and glass radiation properties will be presented.
