Theoretical Model for the Effect of Temperature on the Fluorescence Spectrum of Laser Dye (Rh6G) in Acetone

Abstract

In this research, the effect of temperature change on the fluorescence intensity for Rhodamine 6G (Rh6G) in acetone from room temperature to freezing point of solvent by using liquid nitrogen was studied experimentally and theoretically. As we have noted that the increased temperature led to less intensity and increasingly broader spectrum. We estimate theoretical model for this effect, and the theoretical equation was Extra Val equation.
