Photophysical, photochemical and laser behavior of some diolefinic laser dyes in sol–gel and methyl methacrylate/2-hydroxyethyl methacrylate copolymer matrices

Abstract

The photophysical properties such as singlet absorption, molar absorptivity, fluorescence spectra, dipole moment, fluorescence quantum yields, fluorescence lifetimes and laser activity of 1,4-bis (β-Pyridyl-2Vinyl) Benzene (P2VB), 2,5-distyryl-pyrazine (DSP) and 1,4-bis(2-methylstyryl)benzene(MSB) diolefineic laser dyes have been measured in different… (More)
