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

在本项目中，我们尝试了改善光陶瓷的性能，并探索了基于水溶液工艺的新型光陶瓷，通过光照射发挥了功能。例如，在光陶瓷性能的改善方面，我们已经成功地利用水分散硅化合物的水溶液方法合成了高效和明亮的荧光粉，并成功地实现了分解水的光催化剂和超亲水材料的高功能化。在探索新型光敏陶瓷方面，人们发现了硅酸盐、氮氧化硅和硫代硅酸盐等多种光敏陶瓷。此外，我们已经对它们进行了高度功能化，一些公司正在努力实现它们的实际应用。

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.
