摘要：

Subphthalocyanine and subnaphthalocyanine dyes and their mixture were investigated by means of the spectroscopic and photoelectric methods. Absorption, fluorescence, steady-state and time-resolved photothermal measurements for the dyes and their mixture were done in order to get information about the radiative and non-radiative deactivation processes as competetive processes to charge separation. It was shown that energy transfer between the dyes improved the photocurrent generation in photoelectrochemical cells (PEC) based on In2O3 and SnO2 as an electrode. The possible participation of the dye triplet states in non-radiative processes was discussed. (C) 2003 Elsevier Science B.V. All rights reserved.
