UV–visible and infrared absorption spectra of gamma irradiated CuO-doped lithium phosphate, lead phosphate and zinc phosphate glasses: A comparative study

Spectroscopic and laser properties of Er3+ doped fluoro-phosphate glasses as promising candidates for broadband optical fiber lasers and amplifiers

“…The band around 525 cm -1 is due to bending vibrations of O-P-O linkages in the Q 3 units. The band around 750 cm -1 is due to the symmetric stretching of P-O-P in Q 1 units [13]. The band around 900 cm -1 is due to asymmetric stretching of P-O-P linked with linear meta-phosphate chain and P-F groups in Q 2 units [14].…”

White light emission from γ-irradiated Ag/Eu co-doped phosphate glass under NUV light excitation

“…Elbatal and H.A. Elbatal [25][26][27] ␥-irradiation [16]. However, to the author's knowledge, the effect of silver particles on the emission properties of Eu 2+ ions has been scarcely reported.…”

Spectroscopic and Bonding Properties as A Probe in the Symmetry of PbO-P2O5-ZnO-V2O5 Glass System With Alkali Oxides

“…2). The bands and their assignments are1230 cm-1 caused due to (P-O -) vibrations; 1060 cm -1 bands to PO 4 3-fundamental vibrational mode; 880 cm -1 to asymmetric stretching vibrations of P-O-P groups; 770 cm -1 a symmetric vibration to P-O-P chains and 600 cm -1 to bending vibration of the P-O-P bonds [8][9][10]. FTIR study has, hence, established that alkali oxide entered into the network interstitially as a network modifier and later, depolymerisation is initiated by breaking of P-O-P linkages.…”
