Photobleaching of Rhodamine 6G in polyacrylonitrile matrix

Abstract

The photobleaching of Rhodamine 6G (Rh:6G) in the polyacrylonitrile (PAN) matrix was studied at 5145 Å as a function of temperature. Photobleaching yield numbers were measured at room temperature and 106 °K. The quantum efficiency for fluorescence and the absorbtion cross sections were measured both for the solid polymer dye system and the liquid monomer dye solution. The observations were compared to Rh:6G in polymethylmethacrylate (PMMA). The PAN+Rh:6G system compares well to the PMMA+Rh:6G system and offers some advantages. Laser action was induced in a PAN+Rh:6G system in a longitudinally pumped polymer plate.
