Abstract: The fluorescence spectra and lifetimes of the ternary due mixture C440/C540/Saf. -T were studies. Experimental results indicated that there are efficient energy transfer among these three components of the dye system. Consequently this system may he expected to be a potemtial eandidate of laser dye giving out output in three different wavelength regions. From. the relation of donor fluorescence lifetime as a function of aceeptor concentration and the relation of accepter fluorescence intensity as a funotion of acceptor concentration and the relation of accepter fluorescence intensity as a function of donor concentration, the main mechanism responsible for energy transfer in this system is suggested.
