Spectral and luminescence characteristics of three laser dyes incorporated into xerogel matrices preliminarily calcined under 700oC were studied in the spectral range of 600–700 nm. A stabilizing effect of these matrices on the dye molecules in the S1 exited state was revealed. This effect manifested in decreasing nonradiative losses in this state and increasing the quantum yield of the dye luminescence in a calcined xerogel as compared with methanol.
