The team led by Prof. Shen Dezheng, State Key Laboratory of Luminescence and Applications, Changchun Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, made progress in the research of Group II oxide laser materials and devices. The related achievements won the first prize of Jilin Province Natural Science in 2015, Since the establishment of the award, the first Jilin Province Natural Science Prize won. II oxide, represented by zinc oxide, is a wide-bandgap semiconductor with a large exciton binding energy and is expected to realize a low-threshold ultraviolet semiconductor laser, and thus has wide potential applications in fields such as secure communications and precision machining. Therefore, it has become an international Semiconductor frontiers and hot spots. However, although many years of research have been conducted experimentally, stimulated emission phenomena have also been observed in zinc oxide thin films, nanostructures and powders, and most of the reports have been based on the results of photoexcitation and the more promising electropumping stimulated It is an international challenge to control the impurities of Group II oxide and its optoelectronic devices. It is a challenge to realize the launch. With the formation of acceptor dopant, high ionization energy and serious compensation, a series of problems have been solved. Researcher Shen Dezhen led the research team to overcome the difficulties. After more than ten years' intensive research on Group II oxide optoelectronic materials and devices, many innovative methods have been put forward, such as material growth, physical property control and device design, Based on the new mechanism and new rule of the group oxide laser, new ideas and new methods including controlling the carrier transport by the dielectric layer, generating the hole and electron recombination emission by the collision ionization are proposed, and the development of such materials and the device The first series of excitonic electroluminescent devices, the first zinc oxide based avalanche detector, and the innovative results of ultrashort threshold laser II and electrically pumped stochastic excitation of the II-oxide family were achieved with a series of core challenges facing the application. He has published more than 400 SCI academic papers in this field and cited more than 6,200 times by SCI. His research has received wide attention and positive comments from domestic and foreign counterparts. He has been cited many times by top international journals such as Nature Photonics, Nature Nanotechnology, Physics Reports And reviews, and is included in the authority of the manual.
