We have proposed a new simple water-assisted solid state reaction method (WASSR) . This process is very simple and can synthesize many nano-ceramics just by mixing of raw materials added a small amount of water below 500 K. For example, Ba₂SiO₄:Eu phosphor can be synthesized at 500 K. The average particle sizes were approximately under 20 nm.
