Abstract: In the present paper, thermoluminescence (TL) study of Eu doped LiNaF<sub>2</sub> phosphor is reported. A polycrystalline sample of LiNaF<sub>2</sub>:Eu<sub> </sub>was prepared by solid state diffusion method. Formation of compound was confirmed by taking the X-ray diffraction (XRD) pattern. TL glow curves of <img src='/image/spc_char/gamma2.gif' border=0>-irradiated LiNaF<sub>2</sub>:Eu<sub> </sub>sample show one glow peak at temperature 168°C. The trapping parameters associated with the prominent glow peak of LiNaF<sub>2</sub>:Eu<sub> </sub>are calculated by using glow curve shape (Chen’s) method. The release of holes/electrons from defect centers at the characteristic trap site initiates the luminescence process in this material. The intensity of the TL glow peaks increases with increase of the <img src='/image/spc_char/gamma2.gif' border=0>-ray of <sup>60</sup>Co dose to the sample. A linear TL response is observed in LiNaF<sub>2</sub>:Eu<sub> </sub>in a long span of exposures and it may be used as a TLD material.
