“…882 cm −1 band was stemmed from deformation mode P-O-P of Q 1 pyrophosphate. The band which appeared at 1073 cm −1 was assigned to phosphorus oxygen (P-O) asymmetric stretching oscillations in the Q 1 pyro phosphate [19]. The band in the region 1248 cm −1 was due to asymmetric stretching vibrations of P-O in Q 2 meta phosphate [20].…”

Erbium activated fluorophosphate glasses were synthesized with conceived characteristic combination, 59.5NH4H2PO4+15ZnO+15BaF2+10X+0.5Er2O3(X = LiF, NaF, CaF2, SrF2, AlF3) by melt quenching route. Based on the mass densities, and refractive indices, other physical properties i.e., dielectric constant (ε), reflection losses, molar refraction, internuclear distance and molar volume are determined. XRD has confirmed the non-crystalline character of the prepared glass samples. FTIR, FT-Raman have been employed to study the structural characteristics. Various radiative properties have been inferred through optical absorption measurements by standard Judd–Ofelt procedure. By excitation at 379 nm, all the glass hosts doped with constant concentration 0.5 mole% of Er3+have yielded intense green emission peak due to the transition 4S3/2 → 4I15/2 at 545 nm. Characteristic emission transition 4I13/2 → 4I15/2 at wavelength 1.53 μm has been studied extensively. Particularly the parameters related to that transition namely, stimulated emission cross-sections (σ e) and optical gains (G) are calculated from emission spectra. Among all the fluorophosphate glasses, the one which has shown higher σ e, and G values is sodium fluorophosphate (NFPE) glass. It is recommended for optical fiber amplification and NIR laser usage.
