20世纪是电子产业的世纪,21世纪将是“光子”产业的时代。有关光子与电子的耦合行为,其诱发的化学、物理和生物过程以及应用将成为学术界和产业界最受关注的研究领域。近年.随着成膜技术、纳米粒子技术、激光技术以及测定表征技术（如 STM、AFM和显微拉曼等）的发展,光电化学的研究进入了一个崭新的时期并显示出极大的应用前景。这些研究都属于多学科交叉的前沿学科。现在,虽然从基础到应用都还处于初期研究阶段,但已崭露头角。进一步的研究不仅可以使其在基础领域有较大的学术突破,而且在新能源开发、信息处理、环境保护、新型太阳能电池等领域可能导致许多应用价值很高的新技术的诞生。它将成为二十一世纪一个重要的研究和产业领域。本文将着重介绍氧化物半导体薄膜光电化学研究领域的一些新进展。
The 20th century is the century of the electronics industry, and the 21st century will be the era of the “photon” industry. The coupling of photons with electrons, their induced chemical, physical and biological processes and their applications will be the areas of most interest in academia and industry. In recent years, with the development of film-forming technology, nanoparticle technology, laser technology and determination of characterization techniques (such as STM, AFM and Raman microscopy), the research of photoelectrochemistry has entered a new era and shows great application prospect. These studies belong to the interdisciplinary frontier disciplines. Now, although the fundamentals to the applications are still in the early stages of research, but it has emerged. Further research can not only make it have more academic breakthroughs in basic fields, but also lead to the birth of many new and valuable technologies in the fields of new energy development, information processing, environmental protection and new solar cells. It will become an important research and industrial area in the 21st century. This article will highlight some recent advances in the field of photoelectrochemistry of oxide semiconductor thin films.
