Preparation and second-order nonlinearity of organic/inorganic hybrid materials doped with organic chromophore

Abstract

A kind of hybrid material was made through sol-gel process with the PMMA, TEOS, and 4-(N)-ethyl-N-(2-hydroxyethyl) amino-4'-nitro-azobenzene (DR1). And thefilms of sol were prepared by using the spin-coated method. Through all optical poling, it could be found that there exists an optimum thickness for film. In addition, the higher of sample temperature was, the smaller intensity of SHG was. The experiment showed that the SiO2 network was existent, and hybrid materials significantly improved orientation stability. PACS: 42.65.Ky
