Enhanced Photoluminescence of Eu, Ag-doped SiO2 gel Based on AAO

Abstract

Abstract: Porous alumina covered with europium doped silica sol-gel film exhibited strong Eu ²⁺ related photoluminescence at 396 nm at room temperature( λ_ex=310 nm). The intensity of the photoluminescence can be increased by using porous matrix, thicker gel film and lower annealed temperature due to more photoactive species on the surface. Ag particles can improve the photoluminescence by affecting the surrounding electron field of Eu ²⁺.

Key words: Enhanced photoluminescence, Porous anodic alumina, Sol-gel
