다국어 초록 (Multilingual Abstract)

The YRO_4(R=As, Nb, P, V)blue emitting phosphors were prepared by the combinatorial chemistry method. The quaternary combinatorial library was designed to investigate the luminescence of the host material under UV and VUV excitations(254, 147㎚). In view of the luminescence yield, YAsO_4 rich region was found to be optimum under 254㎚ excitation. It was found that the phosphor synthesized at 1,200℃ with Y(As_0.4P_0.4V_0.2)O_4 composition had a maximum emission intensity. However, the results under 147㎚ excitation were different from those of 254㎚ excitation, the samples of the composition containing a large amount of YPO_4 shows the high emission intensity.
