Eu doped YRO4 (R=As, Nb, P, V) red phosphors were prepared by the combinatorial chemistry method. The quaternary material library of tetrahedron-type composition array was designed to investigate the luminescence of the host material under UV and VUV excitations (254, 147 nm). The photoluminescent characteristics of the samples were comparable to the commercially available red phosphors such as (Y, Gd)BO3:Eu3+ and Y2O3:Eu3+. In view of the luminescence yield, V rich region was found to be optimum under UV excitation. But the results under VUV excitation were different from those of UV excitation, the samples of the composition containing a large amount of P shows the highest luminescence. Especially, higher luminescence was obtained in Y0.9(As0.06Nb0.06P0.83V0.06)O4:Eu0.1 phosphors than commercial (Y, Gd)BO3 red phosphors under 147 nm excitation..
