Predictions of the Rate Constants of the Radiative Energy Dissipation and the Intersystem Crossing of Some Coumarin Laser Dyes
Author(s): MSA Abdel-Mottaleb*
Dye lasers are commonly used in the optical investigation because their solutions in organic solvents deliver tunable,
coherent emission. They exhibit intense fluorescent, owning to some specific spectroscopic characteristics. One
drawback of the laser dyes is that it shows excessive Triplet-State Losses (TSLs) the lack of theoretical predictions of
fluorescence rates, Inter System Crossing (ISC), and phosphorescence in laser dyes prompted us to report on the
predicted rates of radiative and non-radiative transitions of some laser dyes. Structural engineering by some
substituents that influence the simulated rates of coumarin laser dye derivatives for an efficient operation was
investigated. The NH2 functional group renders the coumarin 120 more fluorescents with reduced TLS than the
other investigated materials... View More»
