Investigation of thermoluminescence enhancement of LiMgPO₄ by doping with Tb: a DFT approach

LiMgPO₄ doped with rare-earth elements has become a material of choice for dosimetric applications. To obtain a material with enhanced properties, knowledge of nature of defects in doped LiMgPO₄ is of much importance.The TSL/OSL signal originates from the recombination /luminescence centers, and the whole process depends on electronic structure of the material. Present study aims to investigate geometry and electronic structure of LiMgPO₄ doped with Tb using density functional theory (DFT). (author). (author)
