In the project, we have attempted improvement of photoceramics' properties as well as exploration of new photoceramics, which exhibit functions by photo-irradiation, based on aqueous solution process. As for the improvement of photoceramicss' properties, for example, wer have succeeded in synthesis of phosphors with high efficiency and brightness by aqueous solution based methods employing a water-dispersible silicon compound, and in high-functionalization of water splitting photocatalyts and superhydrophilic materials. As for the exploration of new photoceramics, various photoceramics including silicates, silicon oxynitrides and thioshilicates have been discovered. Moreover, we have performed high functionalization of them, and some companies are working toward their practical use.

在该项目中，我们尝试改善光陶瓷的性能，并探索基于水溶液工艺的通过光照射表现出功能的新型光陶瓷。在光陶瓷性能的改善方面，例如，我们已经成功地采用水分散性硅化合物通过水溶液方法合成了高效率和高亮度的荧光粉，以及水分解光催化剂和超亲水材料的高功能化。在新型光陶瓷的探索方面，已经发现了包括硅酸盐、氮氧化硅、硫代硅酸盐在内的多种光陶瓷。此外，我们还对其进行了高度功能化，一些公司正在努力将其实用化。
