Summary
Rhodamine 6G dye
Area of Science:
- Photophysics
- Polymer Science
- Laser Dyes
Background:
- Rhodamine 6G is a widely used laser dye.
- Understanding its spectral properties in different matrices is crucial for laser applications.
- Polymer matrices offer advantages over liquid solvents for dye stability and handling.
Purpose of the Study:

- To compare dye behavior in liquid methyl methacrylate (MMA) and solid poly(methyl methacrylate) (PMMA) matrices.
- To analyze the influence of temperature and laser power on emissive properties in both polymer and solvent environments.
Main Methods:
- Spectroscopic analysis of Rhodamine 6G doped in MMA and PMMA.
- Comparison with Rhodamine 6G dissolved in n-butyl acrylate (n-BA) solvent.
- Evaluation of spectral changes under varying temperature and laser power conditions.
Main Results:
- Spectral differences were observed between Rhodamine 6G in MMA, PMMA, and n-BA.
- Temperature and laser power significantly affected the emissive characteristics of the dye in all studied media.
- Polymer matrices showed distinct spectral responses compared to the liquid solvent.
Conclusions:
