An insight into the transition metal dependent structural, optical, and electrical properties of dysprosium doped lithium zinc borate glasses

Abstract

A glass series of Dy³⁺ ions doped zinc vanadium lithium borate with chemical composition xV₂O₅·(10-x)ZnO·30Li₂O·60B₂O₃ (x = 0, 1, 5, 7, 9, 10) with 1.0 mol% of Dy₂O₃ has been synthesized by melt quench method. Efforts have been made to identify suitable optoelectronic material by studying the structural, electrical, photo-luminescence (PL), and optical characteristics of the dysprosium ions in the presence of VO²⁺ ions. PL emission spectra have been explored, depicting that when excited at 386 and 424 nm, the glass matrix is suitable for laser action and at 452 nm, it is apt for cool white light applications.
