摘要：

The low Z polycrystalline LiMgBO3:Dy3+ material has been successfully synthesized by novel solution combustion synthesis and studied for its luminescence characteristics. LiMgBO3:Dy3+ material has shown promising TL sensitivity with a broad dosimetric glow peak at 154 degrees C. Near the tissue equivalent TL phosphor with Dy dopant has half of the TL sensitivity as compared to commercial TLD-100. The kinetic parameters i.e. trap depth or activation energy and frequency factor from the glow curve derived by using peak shape method. The main dosimetric characteristics such as dose response and fading effect are investigated. The state of dopant confirmed using photoluminescence spectra. (C) 2014 Elsevier GmbH.
