Abstract: WO3/YF3:Eu3+ nanocomposite materials were prepared by direct precipitation method and its composition, structure, morphology and luminescent properties were investigated. XRD analysis showed that the nanocomposite is composed of WO3 and orthorhombic YF3:Eu3+. SEM showed that the nanocomposite is irregular flake structure, and it is obvious that many YF3:Eu3+ particles are uniformly deposited on the surface of WO3 flake. The particle size of YF3:Eu3+ nanoparticles is in the range of 10~50 nm. PL indicated that the strongest emission peak at 593 nm can be assigned to magnetic dipole transition of 5D0→7F1. Compared with the pure YF3:Eu3+, the luminescence intensity of WO3/YF3:Eu3+ is obviously enhanced. It showed that the WO3 with local surface plasmon resonance (LSPR) play a role in enhancing the luminescence properties of the shell YF3:Eu3+.
