Nanophosphors synthesized by the water-assisted solid-state reaction (WASSR) method: Luminescence properties and reaction mechanism of the WASSR method

Ceramic materials have been widely used in various applications and are significantly important in our daily life. The various methods for synthesizing ceramics powder materials have been already reported, and the synthesis method is known to considerably affect the characteristics and particle morphology of ceramic powder materials. We have recently developed a novel soft chemical synthesis method, named water-assisted solid-state reaction (WASSR) method, which can be synthesized at low temperatures below 100°C. We further demonstrated the effect and availability of this method on the synthesis process for ceramic oxide materials. In this paper, we review some results for the nanophosphors synthesized by the WASSR method and discuss the reaction mechanism of this method.
