초록
조합화학기법을 이용하여 청색 발광을 하는 YRO4(R=As, Nb, P, V)계 형광체를 합성하였다. 합성한 형광체는 254 nm 및 147 nm 여기 하에서의 발광 세기에 관한 사면체 라이브러리를 완성하였다. 254 nm로 여기 시켰을 때, YAsO4를 중심으로 높은 발광 세기를 보였고, Y(As0.4P0.4V0.2)O4의 조성으로 1,200 ℃에서 합성하였을 때 가장 높은 발광 세기를 보였다. 그러나, 147 nm로 여기시켰을 경우에는 YPO4를 중심으로 해서 높은 발광 세기를 나타내었다.
The YRO4(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 nm). In view of the luminescence yield, YAsO4 rich region was found to be optimum under 254 nm excitation. It was found that the phosphor synthesized at 1,200 ℃ with Y(As0.4P0.4V0.2)O4 composition had a maximum emission intensity. However, the results under 147 nm excitation were different from those of 254 nm excitation, the samples of the composition containing a large amount of YPO4 shows the high emission intensity.
