Effect of V2O5 content on physical and optical properties of lithium bismuth borate glasses

Effect of Heat Treatment on Band Gap of V2O5

“…Other researchers also reported [24] that the absorption edge in V2O5 has an Urbach-rule dependence and above 2.4 eV the absorption happens only due to transition at k  0. Thus, the present results imply that by tuning the microstructure through heat treatment; a situation like semiconductor state to metallic state transition could be affected in V2O5 material by a simple, inexpensive approach such as the one used in the current work.…”

Dielectric dispersion, linear and nonlinear optical properties of Li2O–WO3–B2O3: V2O5 glasses

“…Laorodphan et al 18 have studied the effect of V 4þ and V 5þ ions on the structure of vanadiumlithium-borate glasses by synchrotron-based X-ray absorption spectroscopy and vibrating sample magnetrometry technique. Effect of V 2 O 5 content on physical and optical properties of lithium bismuth borate glasses was reported by Subhadra et al 19 In most of the available literature, the vanadium ions have existed in two stable valance states viz., V 4þ state and V 5þ state in glass network, thereby the properties of Li 2 O-B 2 O 3 glasses were tailor made for potential applications. [16][17][18][19] The lithium-borate glasses containing vanadium ions exhibit semiconducting behavior.…”

Thereby, these glasses are well known for their potential applications in electronic and optical switching devices.…”
