Incident laser power and concentration effects on the fluorescence of R101 dye in PMMA polymer

Incident laser power and concentration effects on fluorescence emission from R101 dye in PMMA polymer have been investigated. Different concentrations of the dye were used. It was found that the fluorescence intensity decreased with increasing of the concentration of the dye as a solution and in PMMA polymer, with a red shift. In addition it was found that the fluorescence intensity increased with increasing of the incident laser power I0.
