New Multifunctional Phosphor Created for White LED Lighting and Optical Temperature Measurement

Researchers from Ningde Normal University have developed a groundbreaking multifunctional phosphor that enhances white LED lighting and optical thermometry, addressing the limitations of traditional methods that utilize yellow phosphors and blue chips. The study, published in Frontiers of Optoelectronics, introduces Bi3+/Eu3+-co-doped Ca2Ta2O7 phosphors capable of tunable color emission from green to reddish-orange, thereby improving color rendering and safety by minimizing blue light exposure risks. This innovative material not only promises more energy-efficient and environmentally friendly lighting solutions, but also presents potential applications in visual thermometers and high-temperature safety markings, marking a significant advancement in material science and lighting technology.
