From December 9 to 12, 2018, the International Workshop on UV materials and devices (iwumd-2018) was held in Kunming, attracting thousands of researchers from France, the United States, Japan, Germany, South Korea and other countries. Dr. Chen Changqing, chairman and chief scientist of the company, was invited to serve as a member of the Organizing Committee of the Congress and made a special report. As one of the few companies in the deep ultraviolet LED industry with core extension, chip and package technology, Hubei DUVTek Co., Ltd. (duvtek) is committed to defining healthy life from "core" with the leading deep UV LED technology, and shared innovative technologies at the conference, and discussed and exchanged with scholars who are also engaged in frontier research in the field of UV materials and devices.

At the iwumd-2018 meeting, Dr. Chen Changqing presented a report entitled "high performance deep ultraviolet light emitting diodes based on thick ain epilayer and moth eye microstructure". The latest research progress of the company is introduced, including the epitaxial growth of AlN material on planar sapphire substrate (FSS), the epitaxial growth of AlN material on nano patterned sapphire substrate (NPSs), the improvement of light extraction efficiency of deep ultraviolet led by moth eye microstructure, etc. all the research results and parameters have reached the international advanced level. The report results have been highly praised and approved by researchers from all over the world Yes. During the meeting, Dr. Chen Changqing had a cordial and friendly academic exchange with young researchers from universities and institutes at home and abroad, including Peking University, Xiamen University, Institute of semiconductors of Chinese Academy of Sciences, national Jiaotong University of Taiwan, Tokyo University of Japan, Seoul University of Korea, University of Sheffield, University of North Carolina, etc To promote the development of deep UV LED industry.
