Title: Yusong Wu: Innovator in Garnet-Based Phosphors

Introduction

Yusong Wu is a notable inventor based in Shiyan, China, recognized for his contributions to the field of phosphor technology. He holds a total of four patents, showcasing his innovative approach to materials science and lighting applications.

Latest Patents

Wu's latest patents focus on green-emitting, garnet-based phosphors, which have significant implications for backlighting applications. These phosphors are characterized by the formula (LuYTbA)(AlB)(OC):Ce,Eu, where A can be Mg, Sr, Ca, or Ba, and B can be Ga or In. The inclusion of both an alkaline earth and a halogen distinguishes these phosphors from existing technologies. Their peak emission wavelength ranges from about 500 nm to 540 nm, with one embodiment demonstrating an emission at 540 nm. The full width at half maximum (FWHM) of the emission peak lies between 80 nm and 150 nm. These innovative green garnet phosphors can be combined with red-emitting, nitride-based phosphors, such as CaAlSiN, to produce white light.
