Polycrystalline NaSOF: Eu phosphor prepared by a wet chemical method has been studied for its thermoluminescence (TL) characteristics. The TL glow curve of the compound has a prominent peak at 200 C and may be useful for TL study. TL sensitivity of the NaSOF: Eu phosphor is found to be more sensitive than that of TLD-CaSO: Dy. TL glow curve of the NaSOF: Eu gives a better understanding of the TL mechanism (peaking at 200 and 290 C) involved in the concerned phosphor. In this paper we report TL characteristics of NaSOF: Eu halosulphate phosphors first time.
