摘　　要：利用单光子计数技术测试了新型三元若丹明激光染料在不同溶剂中的荧光寿命、荧光光谱及其寿命的实验数据 .实验表明 ,所研究的三元若丹明染料存在着有效的分子内能量传递过程 ,这些过程使得激光染料的荧光量子效率及光稳定性明显改善 .The fluorescence spectra in various solvents for trichromophoric rhodamine laser dyes, in which naphthalimide chromophores were connected with rhodamine 6G by-CH_2CH_2-, have been investigated. The fluorescence lifetimes of these dyes have been measured by singlephoton counting technique. The intramolecular energy transfer and charge transfer between antenna naphthalimide moieties and rhodamine has been discussed.\;
