Paper Abstract

New results on the influence of the composition of a silica gel-matrix and the process of its production on the spectral, lasing and photochemical properties of embedded luminophores: rhodamine, phenalemine, oxazole, coumarine and other dyes series, which have lasing in the UV, blue-green and red spectral regions under excitation by poweful laser radiation of various wavelength (308 and 532 nm) and intensity (from 0,1 to 100 MW/cm2) have been obtained. The shortest-wavelength lasing is achieved for silica solid matrices with para-terphenyl (342 nm). Optimal conditions have been selected and the lasing of thin silica solid films doped with aminocoumarine (457 nm) with resource exceeding that in solutions has been obtained. It is established, that organic luminophores are fixed in nanodimensional pores of silica and hybrid matrices by specific interactions, that compete with the association of dyes.
