Popis:	Composite powders mixed with yttrium aluminum garnet (YAG:Ce) and SiO2 powders were prepared in a tetraethyl orthosilicate solution of an alkali hydrolysis bath. The state of the composite powders varies depending on the reaction conditions: the amount of ammonium water and the reaction time. The photoluminescence property of the composite powder was the same as that of pure YAG powder, while the quantum efficiency varied depending on the morphologies of the composite powders. The quantum efficiency improved for the composite powder with nano-sized silica particles covering the YAG surface.
