Abstract

Using a modified sol-gel method, LiLa(MoO₄)₂: Tm ³⁺/Ho³⁺/Yb³⁺ phosphors with tailorable up-conversion (UC) emission colors were prepared. Under the excitation of a 980 nm laser diode, up-conversion red and green emissions in Ho³⁺/Yb ³⁺ co-doped and blue emission in Tm³⁺/Yb³⁺ co-doped LiLa(MoO₄)₂ were observed, respectively. The intensities of the RGB (red, green, and blue) emissions could be controlled by varying concentrations of Tm³⁺ or Ho³⁺, and the optimal composition was also determined. In Tm³⁺/Ho³⁺/Yb ³⁺ co-doped LiLa(MoO₄)₂, the UC emission colors could be tuned from blue through white to yellow by adjusting the concentrations of Tm³⁺ or Ho³⁺. The UC excitation mechanisms were also investigated based on the power dependence of UC luminescence intensity.
