Investigating The Effects of The Different Rhodamine 6G Laser Dye Volume Ratios on The Optical Properties of PMMA/PC Films
Rhodamine 6G–polymethylmethacrylate/polycarbonate (Rh6G–PMMA/PC) were prepared by a casting method at room temperature with diverse volume ratios of Rh6G dye solution (5, 10, 15, 20 and 25 ml). The as-prepared films were categorised via UV–Vis spectrophotometer, and the optical properties were investigated in the wavelength range of 200-800 nm. The absorption peaks for pure PMMA/PC film were affected by inserting Rh6G dye solution. Moreover, new peaks appeared and were absorbed whilst the energy band gap was not influenced.
