Abstract
Photo Transfer Thermoluminescence (PTTL) is the phenomenon in which Thermoluminescence (TL) is observed when the material is shined with UV light after routine TL readout. In PTTL the carriers from deep traps are transferred to the shallow traps after the material is shined with UV light. When UV exposed material is heated it gives TL. Up till now this phenomenon is observed only using UV light in many materials. Recently we have developed LiF:Mg,Cu,P OSL material in which OSL comparable to commercially available Al2O3:C is observed. In this material the TL intensity of main dosimetric peak gets enhanced by two times after the OSL readout. This phenomenon is similar to PTTL but the wavelength of light is in blue green region.
