Abstract LaPO4:Eu3+ nanophosphors with different sizes were prepared by hydrothermal reaction with different phosphorus sources. The results by XRD show that all products were ascribed to monoclinic crystal. The size of the products became larger and the crystallization was improved after heat treatment at 900oC. The compared results of the emission intensity of samples with different sizes under different excitations showed that the effect of the crystal size on the emission intensity of the samples excited under UV and VUV sources is quite different.
