PATTERN FORMATION AND QUASICRYSTAL STRUTURE IN AZOBENZENE POLYMER FILM 

报道了偶氮苯聚合物薄膜中的斑图形成 ,横向效应及准晶结构 .用简并四波混频实验手段 ,通过扫描电子显微镜和偏光显微镜观察发现有机薄膜中有许多小岛形成的斑图并形成准晶结构 .实验证明通过写入光偏振态的适当组合可以控制有机薄膜中斑图结构 .为有机薄膜的纳米结构技术开创了一条新路 .

Pattern formation and transverse effect are reported for azobenzene polymer film.We show,through scanning electron microscopy and polarizing optical microscopy investigation of azobenzene polymer film after being irradiated by degenerate four\|wave mixing,that many peak\|like islands of azobenzene polymer molecules array in some patterns.Experimental evidence that it is possible to control the photoinduced micro\|patterns of the nonlinear organic film via adequately polarized write beams and appropriate power of the write beams,thus making easy growth of nanostructures crystals in azobenzene polymer film.
