| 摘 要： | 文章采用直接浸泡法在多孔硅中嵌入了新型共轭有机聚合物聚4-（N,N-二甲基胺丙氧基）苯-4,4’-二苯胺-9,9-二辛基芴-4,7-二噻吩-2-基-2,1,3-苯并噻二唑]（PFTD）,对比研究了多孔硅,PFTD/多孔硅,PFTD/硅以及PFTD在甲苯溶液中的光致发光特性。实验结果表明：PFTD/多孔硅复合膜光致发光强度要明显强于PFTD/硅,同时由于聚合物在固态时有效共轭程度增加导致PFTD/多孔硅复合膜的荧光光谱相对于甲苯溶液中的红光聚合物光谱有所红移。

| Abstract: | In the paper,red-emitting polymer(PFTD) film was coated onto the surface of porous silicon(PSi).The photoluminescence of PSi,PFTD/PSi,PFTD/Si,and PFTD in toluene was investigated.The experiment results showed that the luminescence intensity of PFTD/PSi was higher than PFTD/Si.Compared with PFTD in toluene and PFTD/Si,the photoluminescence spectra of PFTD/PSi showed a red shift,which were attributed to enhancement of conjugate of polymer in solid state. |
