High performance of near-infrared emission for S-band amplifier from Tm3+-doped bismuth glass incorporated with Ag nanoparticles

The significant enhancements of Tm3+:1.47 μm fluorescence intensity in silver nanoparticles embedded bismuth glass is observed. A novel series of glass system with the composition of 60Bi2O3–20SiO2- 20Ga2O3–1Tm2O3-xAgNO3 (where x = 0.0, 0.1, 0.5, 1.0, 1.2, 1.5, 1.7 and 2.0 mol%) were prepared by the melt-quenching method and subsequent in-situ thermal-reduction technology. X-ray diffraction patterns indicated the amorphous nature of as-made glass. Transmission electron microscopy image confirmed the homogeneous dispersion of silver nanoparticles with 7.5 nm average diameter in glass. According to the absorption spectra, the local surface plasmon resonance band locates around 477–570 nm and shifts towards the longer wavelength with the increasing silver content. Under excitation of a 800 nm laser diode, the 1.47 μm emission intensity undergoes significant enhancements by as much as 6 times, which is mainly attributed to the intensified local electric field of silver nanoparticles. Large magnitude of full-width at half-maximum, emission cross section, figure of merit of the 1.47 μm emission are calculated to be 128 nm, 4.8 × 10−21 cm2 and 6.14 × 10−26 cm3, respectively. These results indicate that the present glass is a promising gain medium for S-band optical amplifiers.

Structural and spectroscopic studies on the concentration dependent erbium doped lithium bismuth boro tellurite glasses for optical fiber applications

High gain and better optical properties are the key requirement for the optical fibers and amplifiers to meet the current technological demand. In this regard, in the present investigation, erbium doped lithium bismuth boro tellurite glasses are prepared using melt-quenching technique. The prepared glasses were extensively characterized through, XRD, DSC, UV–Vis-NIR and also Luminescence and Decay techniques to study the concentration dependent structural, optical and luminescence properties. Prepared glasses are amorphous in nature and the corresponding band gap energy decreases with erbium concentration indicates increase of metallicity of the glasses. FTIR studies show different vibration modes majorly borate groups. In addition, Judd-Oflet theory is employed to derive different optical parameters such as intensity parameters, oscillatory strength, branching ratio, stimulated emission cross section and time decay to validate the experimental results of prepared glasses towards optical fiber applications. Estimated values of Stimulated emission, effective band width and gain band width values found higher when compared with other host glasses. Results also show that, 100% branching ratio is obtained for the highest intense peaks corresponds to the transition 4I13/2 → 4I15/2 in NIR luminescence spectra for 1.53 μm broad band. For power dependent 980 nm excitation, up-conversion spectra shows two transitions, namely 4S3/2 → 4I15/2 and 4F9/2 → 4I15/2 at 541 and 655 nm corresponds to green and red emission respectively. From the McCumber’s theory, the absorption and emission cross section more comaprable values are obtained for 1 mol% erbium doped glass. About 40% population inversion is obtained with C band from 1500 to 1550 nm. The results suggests that, the prepated glasses are the potential candidates for optical fiber applications.

Effect of Bi2O3 on mechanical features and radiation shielding properties of boro-tellurite glass system

This paper focuses on the effect of Bi2O3 content (up to 80 mol%) on mechanical features and radiation shielding characteristics of boro-tellurite glasses within TeO2–B2O3–Bi2O3 system. The basic mechanical parameters such as oxygen molar volume, packing density, hardness, and elastic moduli were studied based on Makishima–Mackenzie's theory. The shielding studies of the TeO2–B2O3–Bi2O3 glasses included gamma, electron and neutron radiations. The newly developed Phy-X/PSD program and Geant4 simulation were used to calculate the shielding parameters such as mass attenuation coefficient (μ/ρ), tenth value layer (TVL), mean free path (MFP), stopping power (ψe)), removal cross section (RCS), CSDA range, effective atomic number (Zeff), and half value layer (HVL). The concentration of Bi2O3 content had a significant effect on the gamma shielding competence of the investigated glasses. Form the results of gamma shielding studies, the highest μ/ρ (99.845 cm2/g) occurred at 0.015 MeV for TBB80 and the lowest μ/ρ (0.039 m2/g) occurred at 4 MeV for TBB40. The maximum values of Zeff for gamma interaction occurred at 0.02 MeV and they were 77.26, 78.81, 79.94, 80.80, and 81.48 for TBB40, TBB50, TBB50, TBB60, TBB70, and TBB80, respectively. The gamma shielding features of the investigated glasses were compared with those of various ordinary concretes, and Pb-free, Pb-based, and commercial glasses. The Bi2O3 content had also a considerable influence on the electron shielding competence of the tested glasses. The maximum values of Zeff for electron interaction occurred at 14 MeV and they were 44.58, 47.72, 50.41, 52.75, and 53.73 for TBB40, TBB50, TBB50, TBB60, TBB70, and TBB80, respectively. The results revealed that the bismuth boro-tellurite glasses could be useful for the shielding against gamma, electron, and neutron radiations, wherein the Bi2O3 content can be balanced according to the type and energy of radiation.

Thermo spectral advances of CoO doped alkali bismuth phospho silicate glasses for thermo and photoluminescence applications

The glasses of composition (25-x) LiF–05 Bi2O3–15 P2O–55 SiO2: x CoO have prepared (where ‘x’ is ranging from 0 to 0.5 mol% in step size of 0.1). Prepared samples are characterized by both structural and optical techniques. The results drawn from structural reports suggest that the samples prepared were exhibiting covalently associated interlinked structure. Thermal stability findings from differential thermal analysis disclose that the samples prepared are glassy in nature. X-Ray diffraction reports strongly acclaim the differential thermal analysis conclusions back too. Thermoluminiscence measurements suggest that the sample of 0.4 mol% of CoO concentration exhibiting good shape symmetry factor and low activation energy (~ 0.65) under 15 min of UV - irradiation might be good thermoluminiscence asset. The optical evaluations such as Racah parameters, crystal field stabilization energy and nephelauxetic ratio are additionally projected. The variation in these evaluations with increase in CoO concentration further lead to decrease in optical band gap (~ 2.31 eV) evaluations, which are found to be least for the glass models of 0.4 mol% CoO concentration might be good optical asset to develop novel class of laser active mediums. The radiative evolutions of both emission cross section and transitions probability corresponding to the emissive peaks 2T1g(H) →4T1g(F) &4T1(4P) →4A2(4F) assessed by Photoluminescence technique. All the results drawn from radiative studies are due to octahedrally co-ordinated Co2+ ions and also found to be best for the sample of 0.4 mol% CoO concentration might be useful luminescent resource.

Study of vibrational spectroscopy, linear and nonlinear optical properties of borate-modified tellurium–silica–bismuthate glasses

Quaternary glass system xB2O3−(30−x) SiO2−65Bi2O3−5TeO2 has been prepared by standard melt-quenching technique. The amorphous nature of glass samples has been ascertained by X-ray diffraction patterns. The compositional variations in density, molar volume and crystalline volume have been examined. Analysis of FTIR spectra shows the occurrence of BO3, SiO4 and TeO3 structural units along with both network modifying [BiO6] octahedral as well as network forming [BiO3] pyramidal structural units. The values of indirect and direct band gap energies have been estimated from fitting of experimental data of absorption spectra with Mott–Davis’s model and hydrogenic excitonic model, respectively. Z-scan technique with nanosecond pulsed laser at ~ 532 nm has been carried out to investigate the third-order nonlinear (3ONL) optical properties of prepared glass samples. The values of nonlinear parameters, viz. nonlinear refractive index (n2) and nonlinear absorption coefficient (β), have been estimated by fitting of experimentally observed data with theoretical models, and both are found to decrease with increase in borate content at the expense of silicate content. The 3ONL susceptibility (χ(3)) including real and imaginary parts has been calculated and observed to decrease with increase in borate content.

Effect of different stabilizers on dispersion of gold nanoparticles in bismuth borosilicate glass and their intensity dependent nonlinear behaviour

Here, we report the role of different stabilizers (Eu2O3, EuF3 and KSCN) in stabilizing gold nanoparticles (AuNPs) embedded in Bismuth-Borosilicate glasses. The prepared nanocomposites are characterized by X-ray diffraction (XRD), differential thermal analysis (DTA), UV–Visible transmission spectroscopy, field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), ellipsometery and Z-scan. From FESEM, it has been observed that the morphology of AuNPs is highly dependent on the type of stabilizer. Also HRTEM confirms the covering of AuNPs by stabilizer that prevents the coagulation of NPs. The localized surface plasmon resonance related transmission dip is observed around 585 nm for glass containing Eu2O3 as a stabilizer. The linear and nonlinear refractive index of the prepared glasses is obtained from ellipsometery and Z-scan measurements, respectively. All the Z-scan measurements have been carried out at different input peak intensities varying from 1.9 to 14.38 GW/cm2. Nonlinear optical studies with open aperture Z-Scan shows the switching between saturable absorption and two photon absorption as the laser intensity is increased. The existence of third order nonlinearity has been detected using closed aperture Z-scan in the prepared glasses.

Synthesis and nuclear radiation shielding characterization of newly developed germanium oxide and bismuth oxide glasses

We present the synthesis and nuclear radiation shielding characterization of glasses based on germanium and bismuth oxide prepared with the melt-quenching technique. The glasses were produced using six different compositions as follows (in wt%): 40.0GeO2-60.0PbO, 38.0GeO2-62.0Bi2O3, 31.344GeO2-41.900Bi2O3-26.756PbO, 33.334GeO2-33.333TeO2-33.333PbO, 20.6GeO2-41.9TeO2-17.4Nb2O5-20.1BaO, 41.98Bi2O3-48.26PbO-8.10Ga2O3-1.66BaO. Monte Carlo method (MCNPX code, v-2.6.0) has been utilized for the determination of mass attenuation coefficients (μ/ρ) of the synthesised six different glasses. The acquired mass attenuation coefficients (μ/ρ) have been used to determine the vital parameters for gamma-ray shielding namely half value layer (HVL), mean free path (MFP), tenth value layer (TVL), effective atomic number (Zeff), exposure buildup factor (EBF), energy absorption buildup factor (EABF), transmission factors (TF), respectively. Simultaneously, effective removal cross section (∑R) values for fast neutrons and Proton mass stopping power & proton projected range have been also calculated. The results showed that among all the investigated glasses, 41.98Bi2O3-48.26PbO-8.10Ga2O3-1.66BaO glass sample has the extra capability to reduce nuclear radiation as a shielding material.

Microstructures and mechanical properties of brazed Al2O3/Cu joints with bismuth glass

Abstract Alumina ceramics and copper were vacuum brazed using a bismuth-borate-zinc glass at temperatures between 660 and 720 °C for 20 min. The interfacial phases were characterized and the influence of brazing temperatures on microstructure of the joints were investigated. Shear tests of brazed joints under different conditions were also performed, and the joint fracture was observed and analyzed to determine the influence of brazing temperatures on the joint mechanical properties. Al2O3 ceramic/Al2O3 + glass phase/ZnAl2O4 + glass phase/(Ni, Cu)O/Ni(s.s) + BiNi/copper was identified as the main structure of the Al2O3 joints brazed with the glass. As the brazing temperature increased, the (Ni, Cu)O oxide layer in the joint was observed to thicken and extend to both sides gradually. The amount of BiNi formed in the Ni coating layer increased, and the scattered ZnAl2O4 particles gradually grew. When the brazing temperature reached 700 °C, ZnAl2O4 particles agglomerated on the alumina ceramic side, and glass permeated into the alumina base material. The shear strength of the joint first increased and then decreased with the increase of brazing temperature. The shear strength reached the maximum value of 21.1 MPa when brazed at 680 °C.

Air-brazed Al2O3 joint with a novel bismuth glass

Abstract Polycrystalline alumina ceramics were air-brazed using bismuth glass with a chemical composition of 50Bi2O3–40B2O3–10ZnO (mol.%) at a relatively low temperature. ZnAl2O4 particles were formed insitu in the joints and the particles grew rapidly with an increase in joining temperature and holding time increasing. In addition, penetration of the alumina substrate by the glass became increasingly serious at higher temperatures and holding durations. The mechanical properties of the joints were investigated and the maximum shear strength was determined to be 50 MPa when brazed at 650 °C for 0 min.

Resorbable PCEC/gelatin-bismuth doped bioglass-graphene oxide bilayer membranes for guided bone regeneration

Guided bone regeneration (GBR) is a therapeutic modality applied prior to dental implant placement to increase bone density at the defect site or during placement for directing bone growth around implant. In this study, an asymmetric, bilayer structure was prepared by covalently bonding a dense polycaprolactone-polyethylene glycol-polycaprolactone (PCEC) membrane layer with a hydrogel layer composed of bismuth doped bioactive glass (BG, 45S5) and graphene oxide (GO) particles incorporated in gelatin. Structural and mechanical properties (surface morphology and chemistry, thickness, degradation rate and tensile strength of GBR membranes) were studied. Membranes had a 3D structure having almost 1 mm thickness which is suitable for space filling. Highest tensile strength (TS) (1.71 ± 0.10 MPa, p < 0.001) was observed for membranes having the highest BG containing group (BG20) while lowest TS was observed (1.23 ± 0.11 MPa, p < 0.001) for BG8/GO2 samples. Similarly, hydrolytic degradation of BG20 involving bilayer structures was slower in phosphate buffered saline (PBS) (23% ± 5% in 4 weeks) than other GBR membranes while biodegraded at an equal rate in lipase (BG20 as 72% ± 3%, BG10 as 69% ± 1%, BG8/GO2 as 71% ± 7% and BG2/GO8 as 74% ± 8%). BG8/GO2, displayed lowest gelatin (GEL) release in PBS over 28 d period (175% ± 9% and 164% ± 10% mgGEL/gsample, p < 0.001). However, all bilayer membranes displayed a similar rate of degradation in lipase solution and also had similar mineral deposition ability in simulated body fluid. Significantly higher cell proliferation (p < 0.001) and osteogenic differentiation (p < 0.001) of human dental pulp stem cells were observed in BG20 and BG10 membrane groups than all other groups. On the other hand, GO presence decreased both mechanical and osteoinductive properties compared to pure BG counterparts. Collectively, amine introduced (aminolysis) synthetic dense PCEC layer was covalently bonded to composite hydrogel layer to obtain coherent bilayer membranes for GBR. They were successfully produced to have two layers designed to prevent fibrous tissue movement towards bone defect while enabling bone regeneration. BG20 membrane groups demonstrated higher calcium phosphate deposition TS, cellular growth and osteogenic differentiation.

Crystallization and wetting behavior of bismuth–borate–zinc glass and its application in low temperature joining alumina ceramics

Bismuth glass, 50Bi2O3–40B2O3–10ZnO, was designed, prepared and employed to join polycrystalline alumina with 95 wt.% purity (95Al2O3) in air. Crystallization behavior of the glass was studied. The results showed that Bi4B2O9 and Bi24B2O39 were formed in the glass in the heating process. The glass transition temperature (Tg) and the softening temperature (Tf) were 385 and 419 °C, respectively. Prior to the joining process, the wettability of the glass on the ceramic was studied. The wetting angle of the glass/95Al2O3 system at 700 and 750 °C was 26.6° and 12.6°, respectively, exhibiting excellent wetting performance. Joining parameters influencing microstructure and mechanical property of the joint was researched, showing the in-situ formation of Bi4B2O9, Bi24B2O39 and ZnAl2O4 crystals in the joints when brazed at 600, 625 and ≥635 °C, respectively. The joint microstructure evolved considerably with temperature increasing (T ≥ 635 °C): (i) ZnAl2O4 particles grew steadily (ii) the aggregation of ZnAl2O4 particles was more and more serious, as well as the infiltration of the glass melt into the 95Al2O3. The joint shear strength was proved to be a function of temperature, optimized average value of 58 MPa was acquired when the joints were joined at 625 °C.

Sm3+-doped bismuthate glasses and proton-implanted near-infrared waveguides

Sm[Formula: see text]-doped bismuthate glass has been synthesized by means of the classic melt-quenching technique. Its optical properties were characterized, which included refractive index, absorption and fluorescence spectra. The measured data suggest that the Sm[Formula: see text]-doped bismuthate glass is suitable for optoelectronic applications. A Sm[Formula: see text]-doped bismuthate glass waveguide operating at 1.539 [Formula: see text]m has been manufactured by using the proton implantation with a 0.4 MeV energy and a 8.0 × 10[Formula: see text] ions⋅cm[Formula: see text] fluence for the first time to our knowledge. The effective refractive indices of the propagation modes for the glass waveguide were obtained by the m-line technique. The energy loss caused by the collision of the irradiated protons and the nuclei of the target Sm[Formula: see text]-doped bismuthate glass was calculated by the SRIM 2013. The refractive index profile and the near-field guided mode distribution for the waveguide structure were fitted through the reflectivity calculation method (RCM) and the FD-BPM method, respectively. The proton-implanted Sm[Formula: see text]-doped bismuthate glass waveguide is an alternative for an integrated device in the telecommunication band.

Comparative studies on polarisability, and optical properties of BiZnBo–SLS and PbZnBo–SLS glass

Soda Lime Silica (SLS), mainly composed of SiO2, was utilised in this study as the source of SiO2 for fabrication of glass. A study of physical and optical properties was performed for the glass system of x [RmOn] (0.50−x) [ZnO] 0.20 [B2O3] 0.30 [SLS], where RmOn are Bi2O3 and PbO with x = 0.05, 0.10, 0.20, 0.30, 0.40, and 0.45 mol. The glass was prepared by melt-quenching method. Optical properties of the glass samples were obtained using UV–visible absorption measurements. The main objective of this study was to compare the structural, polarizability, and optical properties of these two series synthesized silica based glass. The structure of the glass system was determined by X-ray diffraction (XRD). The density and molar volume were found to increase as Bi2O3 and PbO concentration increased. The optical band gap, Eopt values for bismuth glasses were between 2.58 and 2.92 eV and varied from 2.42 to 2.92 eV for lead glasses. The highest concentration of Bi2O3 and PbO in glass system showed the smallest Eopt. Bi2O3 glass exhibit the significant value towards direct or indirect band gap in optoelectronic field compared to PbO glass. Refractive index of glass samples was measured by UV–visible spectrophotometer. The value lay between 2.42 and 2.52 for bismuth glass and 2.42 and 2.57 for lead glass and the value increased as bismuth ion (Bi3+) and lead ion (Pb2+) concentration increased. Metallisation criterion was investigated on the basis of refractive index and band gap. The metallisation criterion of the glass sample linearly decreased with increasing concentration of bismuth and lead ions as a result of increasing number of refractive indices and decreasing number of band gap energy. The positive value of metallisation criterion indicates that the glass materials are insulators or not metallic. In conclusion, the obtained results show that the addition of bismuth oxide in silica glass improved its structural and optical properties compared to lead glass.

Facile preparation of plasmon enhanced near-infrared photoluminescence of Er3+-doped Bi2O3-B2O3-SiO2 glass for optical fiber amplifier

This work reports the plasmon enhanced near-infrared emission from Er3+-doped Bi2O3-B2O3-SiO2 glass prepared by conventional melt-quenching method. The silver nanoparticles (NPs) were introduced into glass host as starting constituent not in the form of silver univalent ions, avoiding the complex energy transfer between Ag+ and Er3+. TEM images analysis reveal the homogeneous distribution of almost spherical Ag NPs with average diameter ~6 nm in amorphous glass. Surface plasmon resonance (SPR) band was observed around 495 nm. Interestingly, the near-infrared emission intensity assigned to Er3+:4I13/2→4I15/2 transition undergoes significant enhancements up to 2 times. The peak emission cross section at 1.5 µm is estimated to be 7.3 × 10–21 cm2 on the basis of Fuchbauer–Ladenburger equation. Furthermore, the measured lifetime of Er3+:4I13/2 energy state is prolonged from 1.72 ms to 1.85 ms with the gradual increasing Ag NPs. The silver nanoparticles enhanced near infrared luminescence from bismuth glasses have potential application for optical fiber amplifier.

Optical spectroscopic investigations of neodymium and erbium added bismuth silicate glasses

The bismuth silicate glasses with the composition of 60% by mole of silica and 40% by mole of bismuth oxide were prepared with neodymium and erbium added at 0.1, 0.3, 0.5 and 1 at%. The glasses were melted and the measurement in terms of transmittance was used to analyze absorbance and energy band gap from optical spectra. Neodymium changed the bismuth silicate glass to dark violet color and erbium decolorized the glass with a small addition and turned to light pink when the concentration increased. Transmittance and absorption of glasses changed with the amount of dopant. The major absorption peaks of neodymium added were at 520 and 560 nm and erbium characteristic absorption peaks at 480, 525 and 650 nm.

Preparation, optical and electrical properties of bismuth substituted lead titanate borosilicate glass and glass ceramics

Various composition of lead bismuth titanate borosilicate glasses doped with one mol percent of cerium oxide in the system 55[(PbxBi1−x)TiO3]-44[2SiO2.B2O3]-1CeO2 (0.0 ≤ x ≤ 1.0) were prepared using rapid melt quenching technique. X-ray diffraction study confirmed the amorphous nature of the samples. Structural and optical properties of the glass samples were carried out using infrared spectroscopy, Raman spectroscopy, and UV–vis spectroscopy respectively.

On the basis of the differential thermal analysis, all glass samples were crystallized by given a controlled heat treatment schedule within the temperature range 607–693 °C. For the determination of phase, crystal structure and crystallite size, XRD was also performed on the glass ceramic samples. To understand the surface morphology of the glass ceramic samples, scanning electron microscopy was employed. The dielectric properties were studied with varying temperature at few selected frequencies. The maximum value of relative dielectric constant, εr was found to be 973 at 100 Hz with dissipation factor, D, 3.99 for bismuth free lead titanate glass ceramic sample (x = 1.0).

Stabilization of the δ-Bi2O3-like structure down to room temperature by thermal nanocrystallization of bismuth oxide-based glasses

It has been demonstrated, for the first time, that by thermal nanocrystallization of bismuth oxide glasses one can prepare bulk samples containing the δ-Bi2O3-like phase stabilized down to room temperature. DTA and temperature dependent XRD studies show that the stability range of this phase extends from 20 to ca. 630 °C, i.e. much wider than in bulk Bi2O3 (730–825 °C) and in thin films of pure Bi2O3 (ca 20–500 °C). Between 650 and 730 °C the material adopts the tetragonal β structure. Both δ-like and β phases do not undergo any changes during long-term storage at room temperature. SEM and HRTEM observations show that the microstructure of the material crystallized at 630 °C consists of a large number of small (10–20 nm) grains of the δ-Bi2O3-like phase embedded in the residual matrix. The temperature dependence of the electrical conductivity of the material follows the Arrhenius formula with high activation energy values: 1.4 eV (total conductivity) and 0.96 eV (conductivity of the δ-like phase component). The absolute values of the conductivities are 10−3 S·cm−1 (total) and 2 · 10−2 S·cm−1 (δ-Bi2O3) at 730 °C (extrapolated).

Silver nanoparticle enhanced 27 µm luminescence in Er3+-doped bismuth germanate glasses

This work studied the luminescent properties of Er3+/Ag-codoped bismuthate glass nanocomposites (BGN). Surface plasmon resonance (SPR) peaks characteristic of Ag nanoparticles (NPs) were present at 575–590 nm. Transmission electron microscopy revealed that Ag NPs with different sizes were distributed in the glass matrix. The fluorescence intensity of Er3+ ions at 2.7 μm first increased and then decreased with increasing Ag content, and the maximum fluorescence intensity was obtained under the addition of 1.5 mol% AgCl. Meanwhile, the fluorescence lifetime at 2.7 μm (4I13/2) was extended through the addition of Ag NPs and achieved the maximum value under the addition of 1.5 mol% AgCl. This phenomenon was caused by the local field enhancement of Ag NPs and Ag0→Er3+ energy transfer. The maximum stimulated emission cross-section σem of the Er3+: 4I11/2→4I13/2 transition at 2.7 μm was 1.36 × 10−19 cm2. All the above results indicated that Er3+/Ag-codoped BGN is a promising gain medium for lasers, optical displays, and optical memory devices.

The radiation shielding and optical properties of x [RmOn] (0.5−x) [ZnO] 0.2 [B2O3] 0.3 [SLS], where RmOn are Bi2O3 and PbO with x = 0.05, 0.10, 0.20, 0.30, 0.40, and 0.45 have been prepared by using the melt-quenching method at 1200 °C and was investigated on their physical, structural and gamma ray shielding properties. Field-emission scanning electron microscope (FESEM) data revealed that the particle morphologies is aggregated and irregular in shapes and size. Energy dispersive x-ray spectroscopy (EDS) elemental mapping data confirmed that all mentioned element all present on the prepared glass. Soda Lime Silica (SLS) that is mainly composed of SiO2 has been utilized in this study as the source of SiO2 for fabrication of glass system. From the result, the density and molar volume of both glass samples increased as Bi2O3 and PbO content increased. The gamma ray shielding properties, such as linear attenuation and mass attenuation coefficient, were increased while half value layer (HVL) and mean free path (MFP) were decreased as the increased in Bi2O3 and PbO concentrations. It is recognized that the mass attenuation coefficient value of Bi2O3 and PbO glass are slightly different. From this study, it can be concluded that from the non-toxicity and shielding point of view, the bismuth glass is a good shield to gamma radiation as compared to lead glass.
