Near the turn of this century, the human society will enter rapidly the information epoch in which the problems of energy and environment have been paid extensive attention, and the importance of light in those aspects has been recognized progressively. Here we thank sincerely our guide-deceased, Professor T'sai Liu-sheng,the member of Chinese Academy of Science,the representative of the experimental physical chemistry school in China. It was he who guided as onto the research on photocatalysis,and onto the reasearch on electrophotonic intelligent material later. It was he who estabilished the foundation of the subject-crossing on physics, chemistry and biology in our laboratory. It was he who taught as to follow the development of scientific frontier closely,try hard to adopt modern experimental techniques, and develop the international cooperation broadly. And it was also he who respected fully free-creativenevss and the spirits of advancement of the young, meanwhile, he encouraged the communication of researchers in different fields which is of great importance for those who conduct the interdisciplinary. His unique scientific ideas provided the essential premise for the science creativeness and generation of new thought and ideas. Goethe said that the combination of the wisdom of the older and the capability of the young can create miracle. It is true!^[1]
