  Thermally Stimulated Luminescence and Electron Spin Resonance Study of Gamma Irradiated Poly Carbonate

  By B. Sanjeeva Rao, M. Papi Reddy, A. Raju, S. Kalahasti, E. Venkateshwar Rao

  Abstract: Polycarbonate (PC) is an industrially important polymer. Gamma irradiation effects of PC are investigated by thermally stimulated luminescence (TSL) and electron spin resonance (ESR) techniques. The TSL spectra of irradiated PC have shown two glow peaks, around 149oC (422 K) and 165oC (438 K). The observed glow peaks are analysed by initial rise methods, Chen’s method and modified initial rise method. The trap parameters corresponding to the two glow peaks …

  TSL Studies of Monovalent and Divalent Salts of Polystyrene Sulfonate

  By K. Rajendraprasad, E. Venkateshwar Rao, B. Sanjeeva Rao

  Abstract: AbstractThermally stimulated luminescence (TSL) spectra of monovalent and divalent salts of polystyrene sulfonate (PSS) have been recorded to study molecular relaxations and thermally induced processes. Monovalent salts [sodium polystyrene sulfonate (NaPSS) and potassium polystyrene sulfonate (KPSS)] have shown glow peak around 365 K and 369 K while divalent salts [calcium polystyrene sulfonate (CaPSS) and barium polystyrene sulfonate (BaPSS)] have exhibited two glow peaks around 345 K, 385 K (CaPSS) and …
