8-羟基喹啉铝高分子薄膜的荧光特性

1前言许多的有机化合物在外界条件激发下发出可见光区的荧光，且具有很高的荧光率，如环状化合物及一些具有共轭键的链状化合物等．基于这一特性，许多有机材料成为彩色、大屏幕显示器件等方面应用的理想材料．8一羟基喷淋铝Alq。是这类有机材料中的一种．有关Alq。的文献，虽然对其特性有各种各样的研究t’‘”，然而却没有发现有关Alq。在高分子膜中荧光特性的报导．本文报导了A冲在不同的高分子材料膜中的荧光特性并探讨了各种影响因素，为A你在光学微腔结构的进一步应用提供了一些依据．8一羟基咦淋曾被用在对一些金属离子的分析检测…

The Photoluminesence Characteristics Study on Alq_3 in Polymer Films

In thes pape, the solld state. polymer thin films of 8-hydroxylquinoline aluminum (Alq3) were mad by spdring coat method. The fluorescence efficiencies and the luminscence spectra of them were measured via the laser systeIns. Various experimental factors were considered and tested. It was found tha the peak wavelength of the lundnescence spectra of the Alq3 polymer films shifted and that the purity of the samples affected its fiuorescence efficiencies: the fluorescence deencies of impure sampls were about three-fourth of that of the purified ones; fluorescence efficiencies of Alq3 doped in PMMA polymer was higher than tha doped in PC and PEO.Under certain condihons, transparent thin film 10 layers can be achieved. This kind of polymer thin film of Alq3 exhibits well fluorescence response, bu also has good stability . Spin coat method can greatly reduce the technical requirements comparing with the vacuum plating method.
