Silica-based composite glasses doped with europium(III) crown ether complex, SiO2:[Eu(15C5)]3+, which were prepared by the conventional sol-gel method, showed the red line emissions based on f-f transitions of Eu3+ ion and also gave the f-d blue band emission of Eu2+ ion at 425 nm after irradiating with UV lights around 320 nm for several minutes even in air. The peak intensity of blue emission band increased with prolonging the duration of irradiation, and furthermore such enhancement in intensity still continued even after stopping the UV light irradiation. The 15-crown-5 ether ligands and silanol groups (-Si-OH) in the silica-based matrices played special roles for stabilizing the Eu2+ ion generated by the photo-reduction and the subsequent reduction of Eu 3+ ion without any light irradiation.
