In this paper we have reported excellent luminescence properties of novel nanophosphors synthesized through solgel method with narrow size distribution. The size and morphology of the prepared ZnO nanophosphors has been confirmed through XRD and SEM. We have investigated their photo-luminescence (PL) intensity as a function of wavelength. We have prepared ZnO nanophosphor of size 6 nm. It is observed two different emission peaks near 375 nm in the ultraviolet (UV) and near 525 nm in the visible region. The prepared ZnO nanophosphor has enough potential for optoelectronic applications. Keywords: Dosimetry; Thermo-luminescence; Zinc oxide; Nanophosphors.
In this paper, the novel ZnO nanophosphors is synthesized by solgel method. The study exposed ZnO nanophosphors samples in Gamma (y) radiation to investigate their thermo-luminescence (TL) intensity as a function of temperature. The thermo-luminescence response has been studied in the dose range 0.291.16 kGy and it is observed that the thermo-luminescence response increases with increase in the dose. Moreover, the TL intensity increases with temperature and attains its maximum value near 200 Cand decreases after this temperature. Keywords: Dosimetry; Thermo-luminescence; Zinc oxide; Nanophosphors.
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.
