Eu3＋-doped YPO4 phosphors were synthesized via citric acid-assisted sol-gel process, and their crystal structure and fluorescence properties were investigated. The results show that both heat treatment temperature and heat treatment time have direct influence on phase structure of the products. During the heat treatment,the hexagonal YPO4 · 0.8H20 crystal is generated from xerogel before tetragonal YPO4 crystal is developed from the dehydration of YPO4 · 0.8H2O crystal. Emission spectra of the samples show that the synthesized Eu3＋-doped YPO4 can be effectively excited with 222 nm wavelength light, emittng intense orange-red light at 595 nm and 621 nm. Concentration quenching phenomenon occurs when Eu3＋ dosage is over 8% （molar fraction）. Furthermore,fluorescence properties can be effectively improved by in- creasing heat treatment temperature or prolonging heat treatment time.
