Vibrational properties of samarium phosphate glasses

Influence of modifier oxide on spectroscopic and thermoluminescence characteristics of Sm3+ ion in antimony borate glass system

“…Samarium containing borate glasses are known to have an unusual elastic behavior due to valance instability [17]. Samarium exhibits promising characteristics for spectral hole burning studies [18,19].…”

Spectroscopic and laser properties of Sm3+ doped different phosphate glasses

“…As Eu 3+ ions are hypersensitive to local environments 0925 and microstructures and can be used as fluorescent probe, Yu and Nogani [9] studied photoluminescent changes of Eu 3+ in ZnO-SiO 2 glasses induced by femtosecond laser. Among the numerous rare earth doped glass materials, samarium doped phosphate glasses are known to have an unusual elastic behavior due to valance instability [10]. Although the trivalent samarium ion exhibits a strong luminescence in the visible region (orange), the complicated electronic structure of the 4f 5 configuration is responsible for their neglect.…”

Influence of composition on the structure and properties of SrO–Sb2O3–P2O5 low-melting sealing glasses

“…2. The absorption peak at about 1284 cm −1 is attributed to the P=O bonds stretching vibration and the absorption peak at 1040 cm −1 is due to the stretching vibration of P-O tetrahedra [10]. In addition, the absorption peaks at 912 cm −1 and 775 cm −1 are ascribed to the symmetric and asymmetric stretching vibrations of P-O-P bonds [11][12][13], respectively.…”

“…In addition, the absorption peaks at 912 cm −1 and 775 cm −1 are ascribed to the symmetric and asymmetric stretching vibrations of P-O-P bonds [11][12][13], respectively. The band around 538 cm −1 is the absorption peak of bending vibration of P-O bonds, δ(P-O), of Q 0 tetrahedra [10]. The absorption shoulder at 629 cm −1 is caused by the vibration of P-O-Sb linkages [1,14,15].…”
