conjugated polymer poly(p phenylene vinylene,PPV) was homogeneously doped into silica glass through sol gel technology.Poly(methyl methacrylate) was mixed the complex material to improve the characteristics of optic process.Porous structure with about 100 nm pores was observed by STM.A part of PPV was impregnated in the pores.The process of the excitation and emission was analyzed.
