NIR photoluminescent characteristics of Nd3+ activated fluoroborosilicate glasses for laser material applications

Spectroscopic investigation on the optical characteristics of 1.06 μm (4F3/2 → 4I11/2) transition of Nd3+ ions with different concentration in fluoroborosilicate (FBSND) glasses is reported. The glass transition temperature estimated via DSC analysis confirmed the thermal stability of the Nd3+ doped fluoroborosilicate glassy system. The phenomenological Judd-Ofelt parameters were evaluated by implementing the Judd–Ofelt (JO) theory on the recorded absorption spectrum and the parameters. Strong NIR emission has been observed for the lasing transition at 1.06 μm under an excitation of 584 nm. The emission intensity of all the luminescent bands in the NIR emission spectra of FBSND glasses observed to be increased up to 1 mol% and after that a fall in emission intensity is observed due to concentration quenching. Large value of JO intensity parameters and radiative properties such as branching ratio, stimulated emission cross section, radiative transition probability recommends FBSND glasses for photonic applications.

Emission wavelength selection and tuning in the [formula omitted] manifolds of a Nd:KGd(WO4)2 solid-state laser

We present a Nd:KGW laser with a wavelength selectable intracavity loss scheme comprising a notch filter and external-cavity feedback, which enables distinct continuous-wave laser oscillation regimes. Based on the spectroscopy of the 4F3/2 - 4I11/2 transition in Nd:KGW, we have achieved tunable laser oscillation at either 1067 nm, 1076 nm or 1085 nm corresponding to different spectral peaks of the emission cross-section. An adequate balance of the intracavity loss also allows for dual-wavelength operation at both 1067–1076 nm and 1076–1085 nm peaks, and the inclusion of an additional external reflector permits dual-wavelength oscillation in the vicinity of the main emission peak at 1067 nm. From the external-cavity laser theory perspective, in our approach, the tuning mechanism is treated as an effective intracavity loss instead of an effective reflectivity treatment. The key parameters for further improving the emission wavelength range and tunability are identified and discussed.

Evidence for Participation of 4f and 5d Orbitals in Lanthanide Metal–Ligand Bonding and That Y(III) Has Less of This Complex-Stabilizing Ability. A Thermodynamic, Spectroscopic, and DFT Study of Their Complexation by the Nitrogen Donor Ligand TPEN

The formation constants (log K1) of lanthanide(III) (Ln) ions [except for Pm(III)] and the Y(III) cation have been measured with the ligand TPEN (N,N,N',N'-tetra-2-picolylethylenediamine). These log K1 values show a typical variation with ionic radius, with a local maximum at Sm(III) and a local minimum at Gd(III), with an overall increase in log K1 from La(III) to Lu(III) as the ionic radius decreases. The log K1 for the Y(III)/TPEN complex is much lower than expected from its ionic radius, while the literature log K1 for Am(III) is much higher. The latter effect is thought to be due to greater covalence in the M-L (metal-ligand) bond than for Ln(III) ions: the low log K1 for Y(III) is interpreted as being due to lower covalence. The f → f transitions in the Nd(III) and Pr(III) complexes were examined for effects that might indicate the participation of f orbitals in M-L bonding. The intensity of the f → f transitions in the Nd(III)/TPEN complex was greatly increased compared to that of the Nd3+ aqua ion, which appeared to be due to additional sharp peaks, possibly parity forbidden transitions where parity rules were broken by covalence in the M-L bond. The Pr(III)/TPEN complex showed that all of the f → f transitions shifted to longer wavelengths by some 5 nm, with modest increases in intensity. The effects seen in the f → f transitions of Nd(III) and Pr(III) with TPEN with its six nitrogen donors were present to a much smaller extent in the EDTA and other complexes with fewer nitrogen donors. The changes in the f → f transitions of the TPEN complexes of Er(III) and Ho(III) were small, suggesting a smaller contribution of f orbitals to M-L bonding in these heavier Ln(III) ions. The intense Laporte allowed f → d transitions in Ce(III) complexes show large shifts to longer wavelengths as complexes of, for example, EDTA with increasing numbers of nitrogen donors, suggesting the participation of both f and d orbitals, or either, in M-L bonding. The nature of M-L bonding in M(III)/TPEN complexes was further investigated via density functional theory calculations.

Sensitization of Nd3+ Luminescence by Mn4+ in Mn4+, Nd3+ Codoped K0.5La0.5SrMgWO6

AbstractA series of Mn4+, Nd3+ codoped K0.5La0.5SrMgWO6 phosphors have been prepared by high‐temperature solid‐state reaction method. Under 468 nm excitation, near infrared emission bands centered at around 910 and 1064 nm are observed, assigned to the 4F3/2→4I9/2 and 4F3/2→4I11/2 transitions of Nd3+, respectively. The similarity between the excitation spectra in the 300–550 nm monitored at Mn4+ 697 nm emission and those monitored at Nd3+ 1064 nm emission as well as the lifetime shortening of Mn4+ emission with Nd3+ concentration increasing prove that the occurrence of the energy transfer sensitization from Mn4+ to Nd3+. In terms of the analysis results based on Dexter's theory and Inokuti‐Horayama model, it is believed that the dipole–dipole interaction plays a key role in the energy transfer process.

Superconductivity in infinite-layer nickelate La1-xCaxNiO2 thin films.

We report the observation of superconductivity in infinite-layer Ca-doped LaNiO2 (La1−xCaxNiO2) thin films and construct their phase diagram. Unlike the metal-insulator transition in Nd- and Pr-based nickelates, the undoped and underdoped La1−xCaxNiO2 thin films are entirely insulating from 300 K down to 2 K. A superconducting dome is observed at 0.15 < x < 0.3 with weakly insulating behavior at the overdoped regime. Moreover, the sign of the Hall coefficient RH changes at low temperature for samples with a higher doping level. However, distinct from the Nd- and Pr-based nickelates, the RH-sign-change temperature remains at around 35 K as the doping increases, which begs further theoretical and experimental investigation to reveal the role of the 4f orbital to the (multi)band nature of the superconducting nickelates. Our results also emphasize a notable role of lattice correlation on the multiband structures of the infinite-layer nickelates.

Unconventional metamagnetic phase transition in R2In (R=Nd, Pr) with lambda-like specific heat and nonhysteresis

• The field-triggered metamagnetism with lambda-like peak on the specific heat is found in Nd 2 In and Pr 2 In alloys. • Neither thermomagnetic hysteresis nor lattice changes are observable during phase transition. • Giant magnetoentropy changes of 13.2 J kg −1 K −1 and 19.5 J kg −1 K −1 are achieved with enhanced magnetoelastic coupling. • The max adiabatic temperature changes of 6.5 K and 7.4 K are obtained for Nd 2 In and Pr 2 In alloys under 7 T. • It is proposed to be from the delocalized 5 d electrons evidenced by the negative magnetoresistance. The phase transition of Nd 2 In and Pr 2 In has been studied and found to be between the first-order and second-order nature. Hardly any hysteresis nor obvious cell volume changes are presented. Concurrently the field-triggered metamagnetism is demonstrated with lambda-like peak on specific heat curve. For the field change of 7 T, giant magnetic entropy changes of 13.2 J kg −1 K −1 and 19.5 J kg −1 K −1 and adiabatic temperature changes of 6.5 K and 7.4 K have been achieved in Nd 2 In and Pr 2 In alloys respectively, which is partially contributed by strong magnetoelastic coupling represented by high saturation magnetostriction of ∼450 ppm. Such unique feature is proposed to be originated from the delocalized 5 d electrons, as evidenced by the negative magnetoresistance caused by the phase transition.

Nd:YLF laser at 1053 nm diode side pumped at 863 nm with a near quantum-defect slope efficiency

Laser emission at the 1053 nm transition of Nd:YLF4 is demonstrated using diode-side-pumping at 863 nm directly into the emitting level. The laser configuration uses one total internal reflection at the pump face and provides the highest slope efficiency reported for the Nd:YLF4 medium, close to the quantum limit. In quasi-continuous mode, the laser operates with diffraction-limited beam quality and 78.2% slope efficiency with 14.4 W of output power. In continuous mode, 75.7% slope efficiency in both single-mode and multimode operation is achieved, with 13.5 W output power.

The effect of Nd3+ concentration on fabrication, microstructure, and luminescent properties of anisotropic S‐FAP ceramics

AbstractNd3+ doped strontium fluorophosphate (S‐FAP), with chemical formula Sr5(PO4)3F, nanopowders were prepared using the co‐precipitation method. The prepared powders had no impurity phase with a grain size of about 30 nm and the doping limit of Nd3+ ions in strontium fluorophosphate is about 9 at.%. The morphology and particle size were determined by the doping concentration of Nd3+. Anisotropic Nd: S‐FAP transparent ceramics with different Nd3+ doping concentrations were fabricated successfully by the simple hot‐pressing method. The grain size of prepared S‐FAP transparent ceramics decreased first and then increased with the increase of Nd3+ concentration. The 2 at.% Nd: S‐FAP ceramic presented the highest optical transmittance at all wavelengths range. The characteristic transitions from the ground state to the excited states of Nd3+ ions were observed from the absorption spectra, and the absorption cross‐section was calculated at 3.71 × 10–20 cm2. The influence of Nd3+ ion concentration on luminescence intensity and fluorescence lifetime was studied under 796 nm excitation. The strong emission of 4F3/2→4I9/2 transition in Nd: S‐FAP was calculated by Judd–Ofelt (J‐O) theory.

Physical and spectroscopic characteristics of lithium-aluminium-borate glass: Effects of varying Nd2O3 doping contents

The influence of different Nd2O3 doping contents on the physical and optical properties of the glasses was evaluated. XRD patterns of the as-quenched samples confirmed their glassy nature. Density, ion concentration and field strength increases with the addition of Nd2O3 content, respectively. The absorption spectrum of the glasses exhibit intense peaks at approximately 580, 744 and 800 nm corresponding to the electronic transitions in Nd3+. With increasing Nd2O3 contents, the refractive indices of the glasses were increased from 2.363 to 2.415. FTIR spectra revealed the presence of BO4 and BO3 structural units in the glasses. Emission spectrum of glasses (at 300 nm excitation) displayed four prominent peaks at 368, 421, 483 and 514 nm due to the electronic transition in Nd3+from 4I9/2 to 4P3/2, 2P11/2, 2G11/2, 2G9/2, 4G11/2, and 4G9/2, respectively. The proposed glass system were highly sensitive to the Nd2O3 contents changes.

Luminescence Properties of Lu3+ doped Nd: YAG Transparent Ceramics

Lu2O3 doped Nd: YAG transparent ceramics were prepared by solid-state reaction and vacuum sintering. Ionic size compensation was investigated by comparing the X-ray diffraction patterns (XRD) and Raman spectroscopy (Raman) of (Nd0.06LuxY2.94-x)3Al5O12 ceramics. The micrographs and element mappings of ceramics samples sintered at 1750°C for 50 h were analyzed by scanning electron microscope (SEM) and X-ray energy dispersive spectroscopy (EDS), respectively. The emission peak intensity of 1064 nm is the largest, which corresponds to the 4F3/2→4I11/2 transition of Nd3+. Fluorescence spectra and decay curves show that the fluorescence intensity was the highest when the concentration of Lu2O3 was 0.02, and the fluorescence lifetime was 193.92 µs. The elimination of lattice distortion is beneficial to the improvement of fluorescence properties, which can be attributed to ionic size compensation of Lu3+.

Luminescence behavior of Nd3+ions doped ZnO-BaO-(Gd2O3/GdF3)- P2O5 glasses for laser material applications

In current study Neodymium doped phosphate glasses were prepared and subsequently the Physical and luminescence properties of these glasses were thoroughly analyzed. In total, eleven absorption bands centered at 352, 431, 474, 512, 526, 583, 626, 683, 746, 803 and 875 nm were observed in absorption spectra. Similarly, the emission spectra of the prepared glasses recorded with 804 nm excitation show three radiative transitions peaks at 873, 1054 and 1333 nm. The luminescence properties of present glasses analyzed theoretically as several radiative properties studied through Judd-Ofelt theory. The emission cross section for 4F3/2→4I11/2 transition of Nd3+ ions, measured to be 11.2 × 10−20 cm2 in the case of oxide and 13.10 × 10−20 cm2 in the case of oxyfluoride glass. Similarly, the calculated and measured branching ratio for oxide glass are 54% and 51% respectively, and for oxyfluoride glass the calculated and measured branching ratios are 53% and 55% respectively. From the FTIR spectra it is noted that the bands correspond to the OH group show low transmittance intensity in oxyfluoride glass than oxide glass which is an evident of low OH contents oxyfluoride glass. In conclusion, from the results of present study reveal that the oxyfluoride glasses reported in present work can be a possible material for laser applications.

Optical properties of Nd3+ ions doped GdTaO4 for pressure and temperature sensing

Pressure- and temperature-dependent luminescence properties of 3F3/2 → 4I9/2 transition of Nd3+:GdTaO4 were studied for potential applications in optical sensing. Two isolated emission lines corresponding to 3F3/2 (R2, 1) → 4I9/2 (Z5) transitions, located at 920 and 927 nm under ambient condition, are very sensitive to pressure with coefficients of −15.6 and −14.5 cm−1/GPa determined in a pressure range up to about 9 GPa. The luminescence intensity ratio between the two emission lines exhibits a large dependence with temperature in a range from 80 to 620 K, the corresponding temperature sensitivity at room temperature is similar to that of Nd3+:YAG. These advantages, together with the other observed features of high stable position relationship under pressure and low thermal shifts for the two emission lines indicate that Nd3+:GdTaO4 is a promising candidate to be used as pressure and temperature sensors in the near-infrared spectral range.

Fluorescence of Nd3+ optical centers close to cubic symmetry in a calcium fluoride crystal co-doped with Na+

Earlier, it was shown by the EPR method that at a very low concentration of the Nd3+ ion in the Nd3+:CaF2 crystal, highly symmetric cubic centers with the Oh symmetry are formed. In the present study, the optical centers of the Nd3+ ion with an anomalously long radiative lifetime τR = 13.6 ms of the 4F3/2(1) crystal-field (CF) level in the Nd3+ (0.05 at.%): Na+ (0.2 at.%): CaF2 single crystal at T = 7 K were detected by the method of time-resolved site-selective fluorescence laser spectroscopy. Its fluorescence excitation at the 4I9/2(1) → 4G5/2(1) transition of Nd3+ is in a longer wavelength spectral range compared to optical tetragonal (C4v) L-, orthorhombic (Cs) pair M-, and quartet N- centers. New optical centers exhibit inhomogeneous splitting and can be attributed to nearly cubic sites with symmetry close to Oh. Also numerous Nd3+ optical sites in the Nd3+ (0.03 at.%): CaF2 and Nd3+ (0.05 at.%): Na+ (0.2 at.%): CaF2 crystals at T = 7 K with τR = 240 μs ‒ 8.5 ms of the 4F3/2(1) CF level of Nd3+ were detected in a shorter wavelength spectral range compared to the nearly cubic sites. Among them, the sites with the longest τR = 8.5 ms except for the nearly cubic sites, which were identified as C2v symmetry sites. Their radiative lifetime is about six times that of the C4v site (τR = 1.4 ms). This means that, for optical sites without a center of inversion, the radiative lifetime of the excited state at sites with higher symmetry can be almost an order of magnitude less than at sites with lower symmetry. We explained this result by the different distance between the Nd3+ ion and the ion, which compensates for the excess of its charge. Thus, we have demonstrated the use of the Judd-Ofelt approach to explain the difference in the rates of emission of the excited state in different optical sites of the same rare-earth ion in the same crystal matrix.

Optimization hydrothermal synthesis conditions for nano-sized (Na0.5 Bi0.495 Nd0.005 )TiO3 particles by an orthogonal experiment and their luminescence performance.

By designing an orthogonal experiment with four factors and three levels, (Na0.5 Bi0.495 Nd0.005 )TiO3 (NBT-Nd) nanopowders were prepared using a hydrothermal method under different conditions to determine the optimum hydrothermal synthesis conditions. The synthesized NBT-Nd nanopowders were characterized using X-ray diffraction measurement, ultraviolet-visible spectra, photoluminescence spectra, and transmission electron microscopy to evaluate the orthogonal experimental conditions. The results showed that NBT-Nd powders with excellent crystalline and luminescence properties could be obtained at 160°C, with a 16 h reaction time, 8 mol·L-1 NaOH, and with 0.4489 g C19 H42 BrN. The optimized hydrothermal method-prepared NBT-Nd powder has a rather pure rhombohedral perovskite structure at room temperature, and exhibits an aggregated polycrystalline structure containing nanotubes and nano-sized particles. Under excitation of 247 nm light, strong fluorescence emissions are excited at 423 nm and 441 nm in the NBT-Nd powder that were generated by transitions of Nd3+ from 2 D5/2 to 4 I9/2 and from 4 G11/2 to 4 I9/2 , respectively. Through CIE1931 chromaticity calculation of the emission peaks, the NBT-Nd powder was shown to emit indigo blue fluorescent light.

The polarized optical absorption spectra in the region of a series of the f–f transitions of Nd3+ ions in the Ho0.75Nd0.25Fe3(BO3)4, Nd0.5Gd0.5Fe3(BO3)4, and NdFe3(BO3)4 crystals at 90 K have been compared. The spectral features related to the difference in the local environment of Nd3+ ions in these crystals have been established. In the region of the transition 4I9/2 → 4G5/2 + 2G7/2 of Nd3+ ions in the Ho0.75Nd0.25Fe3(BO3)4 crystal, the appearance of some absorption lines at the structural transition R32 → P3121 around ~200 K due to the local symmetry variation has been found. The intensity of these lines smoothly increases with a decrease in temperature from the transition point. The temperature dependence of the lattice parameters of the Ho0.75Nd0.25Fe3(BO3)4 crystal has been measured. It has been found that, at the transition temperature, the lattice parameter a changes stepwise, which is indicative of the occurrence of a first-order phase transition. The lattice parameter c changes smoothly.

Polarized optical absorption spectra in the range of some f-f transitions of Nd3+ ions in Ho0.75Nd0.25Fe3(BO3)4, Nd0.5Gd0.5Fe3(BO3)4 and NdFe3(BO3)4 crystals were compared at 90 K. Spectral features related to difference of local environment of Nd3+ ions in the mentioned crystals were revealed. In the range of 4I9/2 → 4G5/2 + 2G7/2 transition of Nd3+ ions in Ho0.75Nd0.25Fe3(BO3)4 crystal the appearance of some absorption lines owing to the change of the local symmetry during structural transition R32 → P3121 at ~ 200 K was revealed. Their intensity increases smoothly, when the temperature decreases from the transition point. Temperature dependences of lattice parameters of Ho0.75Nd0.25Fe3(BO3)4 crystal were measured. It was found that at the transition temperature there is a discontinuous change of the lattice parameter a, which indicates a phase transition of the first order. Lattice parameter c changes smoothly.

The effect of 5f states on the nd → 5f transition energies and spectra of americium ions

The spectra originating from the electric dipole transitions of nd (n = 3 − 5) core excited states to the 5f valence states of Am2+ to Am8+ ions have been calculated using the Dirac-Hartee-Fock method, which are compared with the results from the Flexible Atomic Code for the explanation of accuracy. It is found that both the and spectra of these ions consist of two peaks that are well separated in energy respectively by 202.11 eV and 49.10 eV due to strong spin-orbit interaction of the and hole state, while the spectra show a broad quasi-continuum profile.

Synergistic effects of Nd3+ and Ag nanoparticles doping on spectroscopic attributes of phosphate glass

Abstract Efficient, inexpensive and eye−safe new host glass as up−conversion (UC) emission solid−state laser media became demanding. Nanoparticles (NPs) of various noble metals have been inserted into the phosphate−based amorphous host matrix to enhance the rare-earth ions (REIs) stimulated emission cross−section. Furthermore, only a few reports exist on the combined influences of neodymium ions (Nd3+) and pure silver (Ag) NPs on the structural and optical response of magnesium zinc sulfophosphate (MZSP) glasses. In this view, a series of MZSP glasses were doped by Nd3+ ions and pure Ag NPs (at different concentrations) to improve their structural and optical properties. Such melt−quench synthesized glasses were characterized at room temperature using diverse analytical measurement tools. The XRD pattern of as−quenched samples approved their amorphous nature. The FTIR and Raman spectra of glasses revealed the presence of characteristic bonding vibrations of different functional groups. The TEM images showed the existence of spherical Ag NPs (mean size of 8.34 nm) in the host glass matrix. The surface plasmon resonance (SPR) band of Ag NPs was detected around 451 nm. The UV–Vis–NIR absorption and PL emission spectra of glasses were utilized to evaluate the Judd−Ofelt (JO) intensity parameters ( Ω 2 , Ω 4 and Ω 6 ) and radiative properties. The observed fluctuation in the Ω 2 values with the increase in Ag NPs contents was attributed to the dynamic change of ligands symmetry around Nd3+ inside the glass network. Variations in the Ω 4 and Ω 6 values with the increase in Ag NPs contents indicated a considerable reduction in the glass rigidity. The PL spectra of glasses exhibited a prominent band around 576–584 nm corresponding to the 2G7/2 +4G5/2 → 4I9/2 transition in Nd3+. Glass prepared with 0.5 mol% of Ag NPs disclosed the highest PL enhancement (≈19 times) and largest emission cross−section (≈4.35 × 10−24 cm2) which was ascribed to the synergism between Ag NPs SPR mediated strong local field effect (LFE) and the subsequent energy transfer to Nd3+ appeared in the proximity of NPs. It was concluded that the proposed glass composition can lead to the development of UC solid−state laser compared to many other reported glass system.

Luminescence of Neodymium Ion-Activated Magnesium Zinc Sulfophosphate Glass: Role of Titanium Nanoparticles Sensitization

Abstract A series of neodymium ion (Nd3+)-activated magnesium zinc sulfophosphate glasses sensitized with various contents of titanium nanoparticles (Ti NPs) were prepared via the melt-quenching method and characterized. The influence of Ti NPs on the optical characteristics of the glasses was determined. The XRD patterns of the as−quenched samples verified their amorphous nature. The differential thermal analyses (DTA) of the samples showed their good thermal stability against crystallization. The HRTEM image of the samples exhibited the formation of Ti3O5 NPs inside the amorphous network. The SPR bands of Ti3O5 NPs were probed at 587 nm and 730 nm. The ESR spectra of the glasses disclosed the existence of the singlet oxygen induced by the surface plasmon resonance (SPR) effect of Ti3O5 NPs. The absorption spectra of the glasses revealed twelve characteristic bands of Nd3+. The Judd-Ofelt calculations were performed to support the experimental spectroscopic results. The up−conversion (UC) photoluminescence (PL) emission spectra of the glasses revealed an intense yellow band at approximately 585 nm due to the 4G5/2 + 2G7/2 → 4I9/2 transition in Nd3+. The glass prepared with 0.4 mol% of Ti NPs displayed the highest PL intensity enhancement and maximum gain bandwidth. In short, the overall properties of the glasses were sensitive to the contents of Ti NPs. The observed improvement in the optical traits of the proposed glasses was attributed to the Ti NPs SPR-induced local field effect (LFE) in the proximity of Nd3+. Present findings could contribute to the development of the proposed glass-based solid−state laser and photonic devices.

Nd3+ doped magnesium zinc sulfophosphate glass: New candidate for up-conversion solid state laser host

Abstract Phosphate based glasses with neodymium ions (Nd3+) doping are advantageous for high energy short pulse up−conversion (UC) solid−state laser applications. In this work, the magnesium zinc sulfophosphate glass systems with composition of (60−x)P2O5–20MgO–20ZnSO4−xNd2O3 (where x = 0.0, 0.5, 1.0, 1.5 and 2.0 mol%) were prepared via melt−quenching method. Structures of as−quenched samples were characterized at room temperature using Fourier-transform infrared spectrometer FTIR and Raman measurements. Thermogravimetry−differential thermal analyses (TG−DTA) confirmed the thermal stability (>100 °C) of selected glasses. Ultraviolet–visible near-infrared (UV–Vis–NIR) absorption and photoluminescence (PL) spectroscopy were used to evaluate the optical properties of the proposed glasses. Absorption spectra of glasses revealed thirteen characteristic bands in the range of 328–875 nm which were assigned to the ground state to various excited states transitions in Nd3+ ions. The reliability of the Judd−Ofelt (JO) evaluation was authenticated via the attainment of the very low value of root mean square deviation (0.18 × 1020 to 0.63 × 1020 cm2). The spectroscopic quality factors of glasses were enhanced from 1.51 to 2.07 with the increase in Nd3+ ions doping contents. Glass containing 1.5 mol% of Nd3+ ions displayed a slight reduction of Ω2 value, validating the improvement of symmetrical environment around Nd3+ ions in the glass network. Meanwhile, the observed enhancement in the Ω4 and Ω6 values with increasing Nd3+ ions content was ascribed to the improvement of glass viscosity and rigidity. The achieved green−yellowish PL band around 580 nm (emerged from 2G7/2 → 4I9/2 transition) exhibited large branching ratio (83–84%), indicating efficient lasing transition with improved emission cross−section (3.25–4.70 × 10−25 m2) in the glass system. Based on results, the proposed glass system was effective to be used in UC solid−state laser applications.
