The Dependence of Thermoluminescence Response and Glow Curve Structure of LiF(Mg,CU,P) TL Materials on Mg,Cu,P Dopants Concentration

The relationship of TL response and glow curve structure of LiF(Mg,Cu,P) to the concentration of dopants has been investigated systematically. The experimental results have shown that the relative height and light integration of the main glow peak depend strongly upon the technique of preparing the TL material and the proportion of dopants. The change of Mg, P concentration influences principally the height and the width of the main glow peak (210 oC) and the higher temperature peak (250 oC). The change of Cu concentration influences not only the 210 oC, 250 oC peaks, but also the lower temperature peak (110 oC). The present investigation defines an optimum proportion of dopant concentrations and a preparation procedure.
