报道了聚噻吩（P3HT（poly（3-hexylthio—phene））及P3HT与C㈤的衍生物PCBM（6，6-phenyl C61-butyric acid methylester）共混体系的光致发光现象，分析了不同温度热处理对聚噻吩（P3HT）与C60的衍生物PCBM共混体系薄膜的光致发光谱的影响。结果表明，随着热处理温度的升高，P3HT：PCBM共混体系所成膜的峰强度增大，当温度升高至130℃时，共混膜的光致发光谱峰的强度趋于最大，这说明热处理有利于共混体系中高分子链的有序排列。
The phenomance of photoluminescence spectra of poly(3-hexylthiophene) (P3HT) and P3 HT : (6,6)- phenyl-C61-butyric acid methyl ester (PCBM) blend systems was reported. The effect of various annealing treatment on the photoluminescence spectra of poly (3-hexylthiophene) (P3HT) (6,6)-phenyl-C61 butyric acid methyl ester (PCBM) was analyzed, photoluminescence (PL) spectra of blend films showed the PL intensi ty the blend of P3HT: PCBM increase with the increasing of temperature of thermal annealing. At the annea ling temperature 130℃, the peak intensity of photoluminescence spectra of blend films tended to the maximum, which shows that annealing treatment benefits ordered arrangement of polymer chains in the blend films.
