Abstract

Time decay of fluorescence of tris(8-hydroxyquinoline) aluminum (Alq₃) and tris(ruthenium bipyridyl chloride) (Rubpy) in silica, zirconia, tin oxide and ormocer films prepared by the sol-gel method were studied by laser induced fluorescence. The lifetimes of Rubpy are unchanged in the presence of Alq₃ while the lifetimes of the Alq₃ are decreased in the co-doped species as a result of electron transfer or non-radiative energy transfer between Alq₃ and Rubpy. The energy transfer is reflected also by overlap between absorption of Rubpy and emission of Alq₃.
