Eu3+ and Sm3+ single-doped and co-doped YVO4 phosphors have been synthesized and their photoluminescence properties in the VUV–VIS region were investigated. Under the excitation of 405nm, the emission intensity of the optimal phosphor YVO4:Sm3+0.05,Eu3+0.05 at 619nm was largely enhanced compared to that of the sample without Sm3+, owing to the energy transfer from Sm3+ to Eu3+. The mechanism involved...
