摘要
The triplet lifetime of some trichromophoric antenna rhodamine dyes have been measured by nanosecond laser flash photolysis and phosphorescence decay method．The intramolecular triplet energy transfer and intramolecular charge transfer in these dyes have been discussed． These processes may affect the lasing efficiency as well as the emission wavelength of the antenna dyes． The experimental results support the existence folded conformation in the antenna rhodamine dyes linked with CH2-CH2．
