摘要：

Eu3+-doped ZnMoO4 with different doping concentrations were synthesized by a hydrothermal method. The effects of Eu3+doping on the phase structure and photoluminescence（PL） properties of ZnMoO4 were investigated. The result showed that the introduction of Eu3+ could lead to phase transition of ZnMoO4. With the increase of Eu3+doping amount, β-ZnMoO4 was transformed to a phase gradually, which led to different photoluminescence performances. The optimized doping concentration of Eu3+ was 6 mol% for the highest emission intensity at 615 nm. Its CIE chromaticity coordinates were（0.667, 0.331）, which were very close to the values of standard chromaticity（0.67, 0.33） for National Television Standards Committee（NTSC） system.Therefore, Eu3+-doped ZnMoO4 is considered to be a promising red-emitting phosphor for white LED applications.
