聚苯乙烯撑的光致和电致发光特性

The Poto-and Electro- luminescence Characters of Organic Semi-conductor PPV

采用Ｗｅｓｓｌｉｎｇ合成路线制备聚苯乙烯撑［Ｐｏｌｙ（ｐ－ｐｈｅｎｙｌｅｎｅｖｉｎｙｌｅｎｅ）］，测定了它的荧光发射和荧光激发光谱，得知其Ｓ＿１→Ｓ＿０跃迁能为２．３３９ｅＶ．制备了ＩＴＯ－ＰＰＶ－ＡＩ模型发光二极管，测得了它的电致发光谱，并发现了一些有意义的新现象．

Based on Wessling’s synthesis route,the PPV was synthesised.Its S_1→S_0 transition ener-gy 2.339 eV was determined from its fluorescence emission and excitation spectra, An ITO-PPV- Al sandwich-like prototype luminescence diode was fabricated and its electroluminescence spectra were measured.In addtion some interesting new phenomena were observed.
