Abstract

Photoluminescence properties of pristine and Eu2-doped zirconates, viz. BaZr(PO4)2, BaZr4(PO 4)6, Ba2Zr2Si3O 12, and Ca3ZrSi2O9, excited by vacuum ultraviolet (VUV) light using synchrotron radiation were studied. The undoped zirconates show self-activated emission in the 300-340 nm region under VUV excitation, which is ascribed to the Zr4-O2- charge transfer luminescence. Upon doping Eu2 into these compounds, no Eu2 emission was observed in the rest of compounds, except for a weak Eu2 emission observed in Ba2Zr2Si 3O12:Eu2. The quenching of Eu2 luminescence is rationalized as the presence of Zr4-Eu2 metal-metal charge transfer.
