Abstract

The fluorescence emission of Rhodamine 6G (R6G) and Acriflavine dyes in PMMA polymer have been studied by changing the irradiation and exposure time of laser light to know the effect of this parameter. It was found that the fluorescence intensity decreases in the polymer samples doped dyes as the exposure time increases and then reaches stabilization at long times, this behavior called photobleaching, which have been shown in liquid phase less than solid phase. Using 2nd harmonic with wavelength 530 nm laser, the photobleaching effect in the two dye-doped polymers different solvent but same was studied. It was observed that photobleaching of by different solution and by using dip spin coating the photobleaching seem in liquid phase more than the thin films from the mixing solutions with a thickness of (0.1 to 1 micrometer). The maximum peak of fluorescence seems as red shift with different solvent concentration.

Highlights

Polymer doped with different concentrations of dye lasers are the good pipe dream that was as old as the laser itself to have a laser study that is tunable over a wide range of frequency or wavelength
Organic lasing compounds have various applications, especially in the polymer
The polymethyl methacrylate (PMMA) has a good optical transparency and resistance [2] of laser damage properties compared with other polymeric materials that may be used as the transparent polymer matrix

Summary

Introduction

Polymer doped with different concentrations of dye lasers are the good pipe dream that was as old as the laser itself to have a laser study that is tunable over a wide range of frequency or wavelength. The polymers have high homogeneity which is important to get narrow line width spectra of fluorescence, and the researchers can control the physical and chemical composition when the sample formation stage, and there is better compatibility with lasing compounds lasing dyes materials [3].
