Qd. Su et al., PHOTOACOUSTIC AND FLUORESCENCE STUDIES OF RARE-EARTH BETA-DIKETONE COMPLEXES DOPED SILICA-GEL, Gaodeng xuexiao huaxue xuebao, 19(4), 1998, pp. 526-529
A series of rare earth beta-diketone complexes doped silica gel have b
een prepared by Sol-Gel technique, The photoacoustic and fluorescence
spectra of these gel have been measured. Compared with the solid compl
exes, emission peaks of these doped silica gel show redshift while pho
toacoustic absorption peaks blueshift, The intramolecular energy trans
fer processes of Eu-beta-diketones doped silica gel have been studied.
