Luminescent characteristics of a blue-emitting CaAl_2Si_2O_8: Eu~(2+) phosphor and the effect of boron ion substitution

摘要

Blue-emitting CaAl_2Si_2O_8:Eu~(2+)(CAS:Eu~(2+)) phosphor, prepared by solid-state reaction, is described in this paper. We researched the effect of boron ion substitution in the host materials. The phase and luminescent properties were investigated using the powder X-ray diffraction(XRD) and photoluminescence(PL) spectra.
