Abstract:Up-conversion phosphors have attracted considerable attention for their visible-light emission. In this study, a ZnO-TiO 2 up-conversion phosphor containing Yb 3+ and Er 3+ ions was prepared; its emission characteristics and crystal structure were analyzed, and its nanoscale elemental mapping was examined. The metal organic decomposition (MOD) method was used to fabricate the samples. After firing the sample at 1000°C, the emission intensity showed a maximum when the molar ratio was Ti/ Zn/Yb/Er=1/1/0.06/0.0… 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.
