Preparation and Spectroscopic Studies of Rhodamine 6G Doped Polystyrene

In the present work, polys tyrene (Ps) doped with Rhodamine 6G was prepared. The infrared absorption spectra were obtained and dis c u s s e d in the range (400-4000 cm ). A new band appeared -1 2 at 3300 cm due to NH in the spectra of PSRhodamine 6G. In the spectra of Ps – Rhodamine 6 -1 G this band appeared at 1599 ass igned to C = O s tretching vibration. This is due to interaction between the oxy g e n a n d nitrogen atoms in Rhodamine 6G and polys tyrene. The spectrum of pure polys tyrene shows absorption peak at 1069cm this band related to C)H skeletal vibra t io n shifted to -1 1076 cm in polys tyrene with Rhod a min e 6G. The electronic spectra were measured in the range -1 (200-900 nm). Also, the flu o re s cence spectra were s tudied. The electrical properties were measured in the temperature range (300-423 K). The activation energy was calculated and discussed.
