Synthesis, electrostructure and spectral property of oligo-(phenylene vinylenes) with different chain lengths

The syntheses of a series of oligo (phenylene vinylenes) (OPVs) were described. The extended it-chains were built up by sequences of Wittig reactions. Their electronic structures were systematically studied with absorption spectra, photo-luminescent spectra. The influences of the effective conjugation length on the performance of the light emitting devices were investigated.

一维金属光栅嵌入磁性介质纳米结构下的横向磁光克尔效应的增强

本文在一维金属光栅嵌入磁性介质的体系中实现了横向磁光克尔效应的增强.通过最优化金属光栅的嵌入深度来有效激发磁性介质中的波导模式与金属条带上的局域等离激元模式,从而使横向磁光克尔效应的响应得到巨大增强.本文提出了一种用于增强横向磁光克尔效应的新型等离激元微纳结构,这种结构可以应用于高性能磁光器件的设计.
