摘要：

The absorption and emission (fluorescence spectra and radiative decay curves) characteristics of rhodamine 3B and of the molecular forms of rhodamine B are determined in several water/ethanol mixtures. The results are compared to those previously obtained for the related monoethylamine-substituted rhodamines, i.e. rhodamine 6G and the molecular forms of rhodamine 19. Molecular structural factors (alkylation of the amino groups and the protonation or esterification of the carboxyphenyl group) and solvent effects (specific solute-solvent interactions) are investigated. The internal conversion mechanism of rhodamines is discussed.
