| 摘 要： | 研究苯基取代的聚苯撑乙烯共聚物PhPPV和盘状液晶分子HBC-PhC12掺杂不同比例的酰亚胺分子PDI体系的稳态光电流行为.结果表明,PDI含量在0.1%～10%范围时,光生载流子的量子效率与体系的种类和掺杂剂含量无关;PDI含量>10%时,与未掺杂时相比,光生载流子的产率增加2～3个数量级.

| Abstract: | Stationary photocurrrent in phenyl substituted polyphenylenevinylene (PhPPV) and hexabenzocoronene(HBC) doped by perylenediimide(PDI) in a broad range of PDI mass fractions was investigated by steady state photocurrent measurements and using thin films in a light-emitting devices sandwich structure. It is shown that at and above the moderate mass fractions the yield of the charge photogeneration carriers is almost independent of the system and the mass fractions of dopant. As PDI mass fractions >10%,the photogeneration quantum yield increases by two to three orders of magnitude by comparing with the pure system. WT5HZ] |
