Abstract： |
Present invention relates to porous silica luminescence device, belonging to optoelectronics technique field. It features utilizing surface plasma wave Purcell effect enhancing porous silica luminescence. It contains forming surface plasmaguide on porous silica layer, porous silica emissive light coupling to surface plasmaguide- guided mode, then scattering to free air. Due to surface plasmaguide- guided mode density of states is very large, porous silica spontaneous radiation is greatly enhanced, therefore luminous efficiency raising greatly, this make the porous silica becoming the important material used in high efficiency silica-based support luminescence device, and capable of being used in photoelectricity integrating and light interconnection. |
