ResumoThe photophysical and lasing properties of the laser dye pyrromethene 567 (PM567) have been studied by UV/VIS absorption, fluorescence (steady-state and time-correlated), and laser techniques as a function of solvent polarity, dye concentration, and temperature. UV/VIS absorption, fluorescence, and lasing bands of PM567 are mainly affected by the solvent polarity, while the H-bond donor and acceptor ability of the solvents has only a minor influence. These influences are analyzed in terms of the solvent stabilization on the resonance structures of the pyrromethene chromophore. Good correlations between fluorescence and lasing properties of PM567 have been observed, the dye showing the highest lasing efficiencies and fluorescences quantum yields in very polar protic solvents.
