Abstract

SiO ₂ added phosphors, CaAl ₂Si ₂O ₈:Eu ²⁺ + xSiO ₂ (x = 0, 1, 2, 3, 4, 5, 6 and 13 mol) were synthesized by a novel liquid phase precursor (LPP) method. The photoluminescence properties of phosphor added by 5 mol of SiO ₂ showed 110% enhancement in the emission intensity compared to the CaAl ₂Si ₂O ₈:Eu ²⁺ phosphor. A broad emission and excitation wavelength was observed approximately from 400 nm to 600 nm centered at 430 nm and from 280 nm to 400 nm centered at 365 nm, respectively. Photoluminescence intensity of the phosphors increased continuously by SiO ₂ addition up to x = 5 mol and then it decreased with further addition of SiO ₂. The observed photoluminescence properties of the phosphors were discussed related to their crystalline structure and morphology.
