Effects of Temperature and Concentration on Spectroscopic Behaviors of Laser Dye


In this work, the fluorescence spectra of an organic lasing dye were recorded at different temperatures and doping concentrations. Results showed that when the donor concentration fixed and the acceptor concentrations varies for two temperatures (room and low) and for both solvents (ethanol and methanol) used in this work, the peaks of emission of donor and acceptor show a small blue shift. However, this blue shift increases with increasing the acceptor concentrations against donor concentration.
