Electrical properties and FTIR spectra of ZnO–PbO–P2O5 glasses

The white light emission properties of Tm 3+ /Tb 3+ /Sm 3+ triply doped SrO–ZnO–P 2 O 5 glass

“…Takebe et al reported that ZnO is widely used to improve the chemical stability of phosphate glasses [13], performing as an intermediate oxide since Zn 2+ owns large ion radius and electronic configuration with 18 outer-shell electrons [14]. Zn 2+ can form either [ZnO 4 ] tetrahedron or P-O-Zn bridges via phosphate chains linkages in the glass network structure [15,16] and improve the thermal stability of phosphate glasses. Likewise, the addition of SrO in pure phosphate glass can significantly improve the thermal properties due to the formation of meta-phosphate structure [17].…”

The effect of copper ions addition on structural and optical properties of zinc borate glasses

“…In order to understand the effect of addition of CuO in the (B 2 O 3 ) 55 ·(ZnO) 45 glass matrix, we analyzed the mid infrared region (400-1650 cm − 1 ) where the vibration modes of zinc borate glasses are active. The absorption band from 602-620 cm -1 ( Table 2) can be due to the Zn-O stretching vibrations in ZnO 4 tetrahedral units [27,28]. For samples containing copper ions this band may be due also to the Cu-O bonds [29,30].…”

Structural Investigations of Cr3+ Ions Doped Alkali Lead Zinc Phosphate Glasses

“…Hence, these glasses find applications in construction of solid state ionic devices, photonic materials and biomedical materials [13][14][15]. Considerable work had been done in recent years on lead zinc phosphate glasses due to their nonlinear optical properties and low melting nature [16][17][18][19][20][21].…”
