Abstract:
Spectral-luminescent and lasing properties of 4РуРО derivatives at XeCl*-laser pumping are studied depending on a solvent (hexane, ethanol, acetonitrile) and concentration. The causes of anomalous long-wave shift of the luminescence spectrum of 4РуРОN(СН3)2 in a polar solvent are discussed using quantum-chemical calculations. The connection between quantum yields of the photoproducts and lifetime of laser medium operation is established. An explanation of the mechanism of photoproducts' formation is proposed.
