Abstract

The photoluminescence (PL) properties of Mn-doped zinc silicates were studied by combinatorial synthesis and characterization technique associated with various process parameters. The material libraries were prepared with composition spreading in Zn and Mn concentration. The PL emission was green or orange, and depended strongly on the stoichiometry of the zinc silicates and the annealing temperature. The orange emission was observed in Mn-doped zinc silicates annealed at 800°C, which attributed to the increase of crystal field in a highly non-stoichiometric α-Zn2SiO phase ((Zn+Mn)/Si <1).
