Y 3 Al 5 O 12 , yttrium aluminum garnet (YAG) single crystals are extensively used as host materials for solidstate lasers. The materials in nano sizes are of immense importance due to their fascinating physical and chemical properties. Nanocrystals of Nd doped YAG were synthesized by low temperature glycol route. This method consists of a mixing of nitrates in an aqueous media at reasonably low temperatures. The Nd doping concentration was optimized and kept at 2 mol%. The prepared material was annealed at different temperatures. Single phase Nd:YAG nanocrystals were obtained at 850 °C. The prepared nanocrystals were characterized by XRD, SEM and TEM techniques for the crystalline phase, crystalline size and structure. The crystalline sizes were obtained in the range of ~20-30 nm.
Yttrium aluminum garnet, Y 3 Al 5 O 12 (YAG) nanocrystals were synthesized by low temperature glycol method. This is a modified sol-gel method performed at low temperature that consists of a mixture of salts, mostly nitrates in an aqueous media. Single phase nanocrystalline YAG was obtained at 850°C, which is much lower than others such as wet-chemical techniques. The structural characterization is done by XRD and transmission electron microscopy. The crystallite size range from 20-50 nm was observed for the materials prepared at 850-950°C.
Y3Al5O12 (YAG) is one of the important and extensively used solid state laser host materials. YAG nanocrystals were synthesized by low temperature glycol method. This is a modified sol–gel method performed at low temperature that consists of a mixture of salts, mostly nitrates in an aqueous media. Single phase nanocrystalline YAG was obtained at 850 °C, which is lower temperature compared to the other methods such as wet-chemical method. This is however, little higher than the material made by alkoxide sol–gel process. The structural characterization is done by powder XRD, SEM and TEM techniques. The crystallite sizes range from 20-50 nm for the materials prepared at 850- 950 °C.
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.
