“…Moreover, this high-intensity laser at 875 nm corresponding to the 4 F 3/2 fi 4 I 9/2 transition is also useful to produce blue light-emitting devices by the monolithic integration of laser emission. 40 Further, the JO intensity parameters (X k ) are used to evaluate the radiative properties like radiative transition probability (A R ), branching ratio (b R ) and radiative lifetime (s R ) for the 4 F 3/2 fi 4 I 9/2,11/2,13/2 transitions of Nd 3+ ion in the PSN10 glass. Radiative lifetime for the 4 F 3/2 level of Nd 3+ ion in the PSN10 glass is found to be 451 ls which is the highest value compared to those of the other reported glasses presented in Table II.…”

Strontium phosphate glasses with various concentrations of Nd 2 O 3 have been prepared by melt quenching method. Absorption and photoluminescence spectra and lifetime measurements have been carried out to obtain the optical properties of these glasses. From the absorption spectrum, intensity and radiative parameters have been evaluated using Judd-Ofelt analysis. Nearinfrared photoluminescence spectra consist of three bands centered at 875 nm, 1056 nm and 1327 nm, among which the highest intensity has been noticed for the band at 1056 nm that corresponds to the 4 F 3/2 fi 4 F 11/2 transition of Nd 3+ ion. Laser parameters such as branching ratio, band width, stimulated emission cross section and gain bandwidth for the 4 F 3/2 fi 4 F 11/2 transition are found to be 0.52, 28 nm, 2.31 9 10 À20 cm 2 and 6.5 9 10 À26 cm 3 , respectively. Decay curves of the 4 F 3/2 level of Nd 3+ ions exhibit a single exponential nature at lower concentrations, while they become non-exponential at higher concentrations (‡ 0.1 mol.%) due to non-radiative energy transfer processes. This feature is also associated with shortening of lifetime from 307 ls to 82 ls when the Nd 3+ ion concentration increases from 0.1 mol.% to 4.0 mol.%. The results have been compared with those of barium and magnesium phosphate glasses and commercial glasses. The results suggest that these glasses have potential applications as infrared laser materials at 1.05 lm.

“…Thus, improvement of the luminescence properties can be achieved only if the optically active ions are incorporated into the low phonon phase which is formed during crystallization. Glass doped with rare earth elements are widely used in laser technology and optoelectronics [8][9][10][11][12][13][14]. Heavy metal oxides doped with selected rare earth elements were the subject of interest for a couple of decades.…”

“…The spectroscopic properties of Nd 3 + ‐doped glasses of different glass matrices have been investigated and studied . However, it was felt that a zinc phosphate glass composition (NH 4 H 2 PO 4 + ZnO + BaF 2 + NaF) doped with Nd 3 + ions exhibited better luminescence properties than other reported glasses.…”

Nd -doped lead-free zinc phosphate glasses with the chemical compositions (60-x) NH H PO + 20ZnO + 10BaF + 10NaF + xNd O (where x = 0.5, 1.0, 1.5, 2.0 and 2.5 mol%) were prepared using a melt quenching technique. Vibrational bands were assigned and clearly elucidated by Raman spectral profiles for all the glass samples. Judd-Ofelt (J-O) intensity parameters (Ω : λ = 2, 4, 6) were obtained from the spectral intensities of different absorption bands of Nd ions. Radiative properties such as radiative transition probabilities (A ), radiative lifetimes (τ ) and branching ratios (β ) for different excited states were calculated using J-O parameters. The near infrared (NIR) photoluminescence spectra exhibited three emission bands ( F level to I , I and I states) for all the concentrations of Nd ions. Various luminescence properties were studied by varying the Nd concentration for the three spectral profiles. Fluorescence decay curves of the F level were recorded. The energy transfer mechanism that leads to quenching of the F state lifetimes was discussed at higher concentration of Nd ions. These glasses are suggested as suitable hosts to produce efficient lasing action in NIR region at 1.05 μm.
