Optical and other structural properties of some zinc vanadate semiconducting glasses

Tunable optical properties of multiphase ZnO–V 2 O 5 polycrystalline powders

“…1 A 1 and 649 nm can be attributed to the 3 T 1 ? 1 A 1 transition [17,18,20]. Hence, the observed strong white-yellow luminesce is a combination of emission peaks due to native point defects of ZnO and characteristic transitions of zinc vanadate phases.…”

“…The V 2 O 5 mole fraction, x, in the polycrystalline samples was varied from 10,15,20, 25, 28, 30 to 33 mol% and are denoted as ZV10, ZV15, ZV20, ZV25, ZV28, ZV30 and ZV33 respectively. For example ZV33 represents ZnO-V 2 O 5 system with V 2 O 5 mole fraction of 0.33.…”

Effects of samarium (III) oxide content on structural investigations of the samarium–vanadate–tellurate glasses and glass ceramics

“…Although V v thus behaves like P v in forming the ions VO 4 − 3 and V 2 O 7 − 4 it shows a much greater tendency than P to form condensed oxy-ions [6]. On the other hand, the V 2 O 5 -rich glasses in which V 2 O 5 acts as the network former have semiconducting and magnetic properties [7,8].…”

Glass formation in the V2O5‐MoO3‐ZnO system

“…According to Bersani et al the main effect of the addition of modifier oxide (ZnO) in vanadate glasses is a transformation of the VO 5 bi-pyramids into VO 4 tetrahedra [8]. Ghosh et al synthesized glasses in the system xV 2 O 5 -(1-x)ZnO x=0.5-0.8 and discussed VO 4 units as main building units [11]. Hubert found that VO 4 tetrahedra are the predominant coordination polyhedra for V atoms in zinc borovanadate glasses containing 10 to 50 mol% V 2 O 5 [3].…”
