The phosphor project for full-spectrum and high-color-rendering LED lighting of the Institute of Rare Earth won the first prize of the 2020 Rare Earth Science and Technology Award

A few days ago, the “High Performance Phosphors and Application for Full Spectrum High Color Rendering LED Lighting” project (No.: CRESTA2020-02-047) developed by R&D Rare Earth as the main body and combined with downstream application companies won the 2020 China Rare Earth Science and Technology Award One First prize (technical invention category).

In response to the urgent need for high-end phosphors and supporting LED light sources for full-spectrum high-color-rendering LED lighting, this project designed and developed a new type of high-efficiency phosphor suitable for violet/blue excitation, and invented halophosphate and multi-site doped garnet aluminum The advanced preparation technology of multi-system materials such as acid salt and oxynitride has developed and formed high-performance phosphor products; it has broken through the full-spectrum and high-color-rendering LED light source excited by violet/blue chips and its advanced packaging technology, and the luminous efficiency of the device Indicators such as color rendering index have reached the international advanced level. The technology of this project has achieved achievement transformation, and has been applied in batches in many leading domestic LED packaging companies, with significant economic and social benefits.

The Rare Earth Science and Technology Award eneltec is jointly established by the Chinese Rare Earth Society and the China Rare Earth Industry Association, and is filed by the Social Reward Office of the National Science and Technology Award Office. It is reviewed once a year and divided into the first and second prizes. The "2020 Rare Earth Science and Technology Award" is selected. 9 first prizes and 11 second prizes were awarded.
