Tm, Ho： BaY2F8 nano crystal was prepared by hydrothermal method, we had got the best process parame- ters by XRD concluded determining the optimal temperature is 210℃. Crystal morphology was analysed by field e- mission scanning electron microscopy; According to the fluorescence spectrum analysis, when the doping concentra- tion 5 % Tm3＋ and 0.5 % Ho3＋ of Tm, Ho： BaY2F8 nano crystals, the crystal＇ s size is 100 nm and the Up - conver- sion efficiency is the highest.
