Photoluminescence Characteristics of the Nano-Sized Red Phosphor(Y$_x$,Gd$_y$)O$_3$:Eu$^{3+}_{1-x-y}$ by Using Liquid PhasePrecursor Methods

Enhancement of photoluminescence properties of CaAl2Si2O8:Eu2+ by SiO2 addition

“…The precursor of SSR obtained by hand-grinding of oxide raw materials is not homogeneous. In contrast, the precursor prepared by liquid phase precursor (LPP) method is considerably homogenous since an aqueous solution of homogeneously mixed raw materials was impregnated into the cellulose fiber cell [13]. The merit of this process is comparably short time at relatively low temperature compared to SSR method.…”
