摘要：
Phosphate glasses with different RE element dopants were prepared by conventional melt quenching method. Dopants like Nd2O3, Sm2O3 and Eu2O3 were added in glass with 0.5% & 1.5% molar ratio. While varying dopant ratio, phosphate glasses exhibits different properties. The XRD characterization reveals the non-crystallinity of the samples. Both FTIR and Raman confine the ionic nature of the samples. The fluorescence emission spectra Nd2O3 shows that the most intense band occurred at 380 nm due to D-4(712) - I-4(3/2) transition but for Sm2O3 and Eu2O3 most intense bands are seen at 375 nm and 379 nm due to the transition (4) D-1/2 -> H-6(5/2) and of (5)G(5) - F-7(0) respectively.
