Design of phosphors in glass doped with silver nanocrystals (Sr,Ca)AlSiN 3 :Eu 2+ for sunlight-like lighting excited by violet light chips

glass doped with silver nanocrystals. The prepared phosphor-in-glass composites not only maintain a quantum efficiency comparable to that of the original phosphor material (around 90%) but also demonstrate excellent chemical stability and remarkable resistance to thermal quenching. When excited by a 410 nm violet light chip, through the incorporation of commercial blue and green phosphors, the modulation of full-spectrum warm white LEDs was successfully achieved. These LEDs feature a color rendering index of 91, a correlated color temperature of 5171 K, and a luminous efficacy of 80 lm/W. This research offers what we believe to be a novel strategy for the design of high-performance inorganic fluorescent packaging materials and shows great potential for the development of next-generation, sunlight-like healthy lighting solutions.
