The improvement in photoluminescence property of CaYAIO_4:Eu~(3+) phosphor by the post annealing process

摘要

This paper describes the synthesis and characterization of the novel CaYAlO_4. Eu~(3+) phosphor, which emits red photoluminescence (PL) with the main emission peak at a wavelength of 611.5 nm by a VUV irradiation (147 nm) at room temperature. The experimental data showed that the post-annealing process has improved significantly the PL property of this phosphor.
