Yttrium aluminum garnet, Y3Al5O12 (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.
