Recently, the list of the "Top Ten Scientific and Technological Innovation Achievements" at the provincial and municipal levels for 2025 was officially released. Hubei DUVTEK Co., Ltd. (hereinafter referred to as "DUVTEK"), a subsidiary of Wuhan UVLEDTEK, was successfully selected for its "High-Efficiency Ultraviolet LED Chip Fabrication Technology."
As the only selected achievement from Ezhou, this technology not only represents a major breakthrough in the field of semiconductor ultraviolet optoelectronics, but also marks a significant step in overcoming long-standing foreign technological monopolies, achieving independent and controllable core chips and devices in China.
Semiconductor ultraviolet LEDs are widely regarded as "the future of high-end UV light sources." They are extensively applied in key fields such as new energy vehicles, biopharmaceutical synthesis, and public health safety. However, the core AlN/AlGaN epitaxial growth technology has long been constrained by foreign technological barriers. After years of dedicated research and breakthroughs, DUVTEK has precisely addressed three major industry challenges-difficult material growth, low chip efficiency, and poor device reliability-achieving full-chain technological advancement, establishing an independently controllable intellectual property system, and reaching a world-class level of technology.
This achievement delivers substantial and tangible breakthroughs across multiple levels. On the materials side, an original high- and low-speed pulsed epitaxial growth technology has been developed, with derived materials successfully applied in the "Haiyang-1" satellite, filling the gap in China's satellite ultraviolet spectrum and supporting major national aerospace projects. On the chip side, innovative photon regulation technology has significantly improved light output efficiency. Related products have been exported to Germany, Japan, and France, establishing a strong presence in the global high-end market. On the packaging side, advanced packaging technologies have been developed, enabling automotive-grade UVC LED sterilization devices with a bacterial and viral inactivation rate of ≥99.9%, far exceeding the industry benchmark of 70% set by leading international manufacturers, and accelerating domestic substitution.
At present, the achievement has been successfully scaled and widely applied in new energy vehicles, smart home appliances, biopharmaceuticals, and national defense sectors, providing strong momentum to enhance China's international competitiveness in these fields.
