A Comparative Investigation of Optical and Electrical Properties of Vanadate Zinc Lithium Phosphate Glass and Nanostructured Glass–Ceramics

In this paper, we investigate the study of glass properties compared to that of glass–ceramics with the composition of the system (in mol.%): 68 P 2 O 5 –20 ZnO–10 Li 2 O–2 V 2 O 5 , which reveals interesting results. Glass sample was synthesized by quenched melt technique. The glass–ceramic composi...

Description
Summary:In this paper, we investigate the study of glass properties compared to that of glass–ceramics with the composition of the system (in mol.%): 68 P 2 O 5 –20 ZnO–10 Li 2 O–2 V 2 O 5 , which reveals interesting results. Glass sample was synthesized by quenched melt technique. The glass–ceramic composites contain fine nanocrystallites embedded in the glass matrix confirmed by XRD. The energy band gap and Urbach energy values were determined from their UV edges. Impedance spectroscopy was used, to investigate ionic conductivity and impedance measurements of the studied samples. The variation of electrical data, as a function of frequency and temperature, was analyzed using the Nyquist graph by applying Jonscher’s universal power laws and the Almond-West formalism. The ac and dc conductivities of all samples increase with increasing temperature indicating the presence of an ionic contribution.
