Paper Abstract

Delayed luminescence spectra of ethanolic solution of RhilO Rh19 Rh6G TmRh RhB and Rh3B at 77 K were investigated. Obtained results indicated that photoionization of the dye molecules being in their triplet states and then recombination of the pair ion electron is responsible for observed delayed fluorescence. Influence of excitation wavelength on the delayed luminescence spectra is presented.
