香豆素衍生物激光染料的研究

Study on Coumarin Derivative Lasing Dyes

合成了四个新型香豆素衍生物激光染料,研究了其中两个染料的吸收光谱和发射光谱的溶剂效应,揭示了染料吸收光谱红移及发射光谱的Stokes红移的内在本质。在YAG染料激光器上对它们的激射性能进行了测试,结果表明,含三氟甲基的两个染料具有优良的激光性能。

Four coumarin derivatives of lasing dyes were synthesized. Two of them which are substituted by trifluoromethyl have good lasing properties. The solvent effects on the absorption and fluorescent spectra of two dyes in organic solvents have been studied with Nicol and Liptay theory. The expected linear relationship between the wavelength and the solvent parameters was obtained.
