Abstract:This work reports, for first time, on optically-driven white light emission from samarium-doped yttrium aluminum garnet ceramic, Sm-doped YAG. Nanocrystalline Sm-doped YAG sample has been prepared via co-precipitation method then transformed to bulk ceramic by sintering process using Spark Plasma Sintering (SPS) technique. X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM) are used to characterize the crystal structure of the nanocrystals. The micro-grains of the obtained cera… 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.
