中文摘要：

分别采用溶液成膜法和原位本体聚合法制备了六苯并蔻/聚甲基丙烯酸甲酯（HBC/PMMA）复合膜,并采用紫外光谱、荧光光谱和荧光绝对量子产率研究了HBC/PMMA复合膜的发光性能.结果表明,溶液成膜法制备的复合膜的荧光强度和绝对量子产率分别是原位本体聚合法的10倍和6倍,但由于PMMA对激发光的吸收,两者的荧光绝对量子产率都较低.随着HBC质量分数逐渐减小,复合膜的荧光强度和绝对量子产率都先增大再降低,绝对量子产率极大值时的HBC质量分数要比荧光强度极大值时的低一个数量级.随着复合膜厚度的降低,荧光强度和绝对量子产率都出现先增大后减小的现象,荧光强度极大值时的厚度为0.44 mm,而绝对量子产率极大值时的厚度为0.56 mm.

英文摘要：

Hexabenzoeoronene/poly （ methyl methacrylate ） （HBC/PMMA） composite film was prepared respectively by solution casting and in-situ bulk polymerization, and the luminescence properties of the as- prepared composite film were investigated by ultraviolet spectroscopy, fluorescence spectroscopy and absolute quantum yield. The results showed that the fluorescent intensity and absolute quantum yield of HBC/PMMA composite film prepared by solution was 10 times and 6 times respectively that prepared by in-situ bulk polymerization, while absolute quantum yield of the two kinds of composite film was very low due to the absorption of PMMA into the exciting light. With decreasing of the HBC content, both fluorescent intensity and absolute quantum yield of HBC/PMMA composite film first increased and then decreased. The HBC content where the absolute quantum yield was maximum was an order of magnitude lower than that where the fluorescent intensity was maximum. With decreasing of the composite film thickness, both fluorescent intensity and absolute quantum yield of composite film first increased and then decreased with thickness of 0.44 mm at maximum fluorescent intensity and 0. 56 mm at maximum absolute quantum yield.
