The “Ceramic method” at high temperature is a conventional synthesis method for the inorganic solids. In this study, we demonstrate a novel low temperature synthetic technique (water-assisted solid state reaction (WASSR)) for the Nano-phosphor materials. The WASSR method is a very simple and can synthesize the nano phosphor materials just by mixing or storing of raw materials with a small amount of water at low temperature (below 573 K). We present the luminescence properties of the phosphor materials prepared by our original WASSR method.
