Abstract

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 850Β°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‐ 950Β°C.
