Abstract

Photoacoustic spectral characteristics of Rh6G and RhB solutions in mixtures and on Al2O3 surfaces are reported. An enhancement of the photoacoustic signal is observed for dye mixtures, between 480 and 530 nm. This could be due to the dominance of the resonance excitation transfer process. In addition, the spectra of the mixtures show a blue shift due to dimer formation in Rh6G. Compared with those, the spectra of Rh6G and RhB on Al2O3 surfaces show red shifts which may be due to photobleaching.
