Polycrystalline halosulphate phosphors are prepared by a wet chemical method. Strong thermoluminescence (TL) was observed in KZnSO4Cl, KMgSO4Cl, Na3SO4F and NaMgSO4F hosts. In these hosts Ce, Dy; Ce, Mn and Ce, Tb the Ce3+ ions acting as sensitizers and Dy3+, Mn2+and Tb3+ ions as activators. The TL glow curves of these halosulphate phosphors exposed to γ-rays for 5 Gy at the rate of 0.995 kGyh-1 are described and discussed first time here.
