Synthesis of photoceramics based on aqueous solution and complex chemistry: Improvement of thier properties and exploration of new photoceramics

在本项目中，我们尝试在水溶液工艺的基础上，改善光陶瓷的性能，探索新的光陶瓷，并通过光照射来展示其功能。在提高光陶瓷性能方面，我们成功地采用水分散硅化合物的水溶液法合成了高效率、高亮度的荧光粉，成功地实现了水裂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，已发现了硅酸盐、氮化硅、硫代硅酸盐等多种光陶瓷。此外，我们已经实现了它们的高度功能化，一些公司正在努力实现它们的实用化。

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.
