Luminescence studies on lithium- strontium borophosphate glasses doped with CR, NI and ZN ions

Abstract

Luminescence material is a solid which converts certain types of energy into electromagnetic radiation over and above thermal radiation. Due to the limited studies on luminescence properties of the transition metal ion doped glass, this present study aiming to understand further the effect of doping different transition metal ions to the luminescence properties. This paper report on the luminescence properties of 20Li2O-20SrO-30B2O3-30P2O5 glasses doped from the photoluminescence spectroscopy. The luminescence spectra of 20Li2O-20SrO-30B2O3-30P2O5-x with x = 1 mol % of different transition metal ions (Cr, Ni, and Zn) which had been prepared by melt quenching technique. The luminescence properties were analyzed using photoluminescence spectroscopy. Based on the emission spectra obtained from 20Li2O-20SrO-30B2O3-30P2O5-Cr, it consists of two emission bands at around 348 nm and 369 nm. While for the luminescence spectra of 20Li2O-20SrO-30B2O3-30P2O5-Ni, it exhibits only one emission band which is at around 363 nm. Lastly, for the luminescence spectra of 20Li2O-20SrO-30B2O3-30P2O5-Zn, it exhibits two emission bands at around 379 nm and 434 nm.
