摘要：

7-Diethyl amino-4-methyl coumarin (DAMC) exhibits amplified spontaneous emission of (ASE) in two distinct bands, one around 425 nm and another around 450 nm in certain aprotic solvents like chloroform, p-dioxane, n-butyl acetate, etc. Experimental investigations indicate that the longer wavelength band is apparently due to the twisted intramolecular charge transfer conformation of the dye (formed predominantly in the excited state and) stabilized by the complex formation with the solvent.
