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 Alq3are 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.
