Li2B4O7 is a low‐Z, tissue‐equivalent material and several phosphors based on this material are proposed for use in dosimetry of ionizing radiations using thermoluminescence. The synthesis of this phosphor using boric acid is a bit tricky as the stoichiometry and the crystallinity of the product depend on several factors. A new synthesis using solid state diffusion is used. The characterization of Li2B4O7: Cu phosphor thus prepared, using XRD, thermoluminescence, and PL techniques is described. It is also shown that the crystalline Li2B4O7: Cu containing monovalent Cu has good TL sensitivity, while glassy Li2B4O7 and divalent Cu are detrimental for TL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
