Fluorescence properties of dyes for 570-800 nm lasing region in sol-gel silica
The spectral-fluorescence characteristics of the dyes for 570-800 nm lasing region: Rh6G, DCM, LD678, and Rh800 were studied with the purpose to clarify an influence of intermolecular interactions in SiO₂ matrix on processes of the excitation energy decay of the laser dyes in S₁ state. Their quantum...
