Abstract:Correlations were studied between the optical absorption (OA) spectra and the integral curves of thermal glow (TG) in 300-600 K after irradiation of Lu2SiO5 : Ce scintillation crystals with 60Co gamma-quanta (1.17 and 1.33 MeV) at the dose rate 1.1 Gy/s in the dose range 70-5·107 Gy at 310 K and their gamma-luminescence (GL). There are intrinsic defects caused by technological process, such as neutral VO5-centers with OA band at 193 nm and charged =Si-VO5 --- 213 nm, Lu1-F^+-Si --- 238 nm, Ce3+/Ce4+ --- 263 nm… Show more
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.
