  • Phosphor, light-emitting device, illumination device and image display device
    Patent number: 10370589
    Abstract: The present invention addresses providing a novel narrowband red phosphor having a high internal quantum efficiency, a short afterglow time, and a large number of emission components in a short-wavelength region with high red visibility. This is solved by a phosphor characterized by including a crystalline phase that has a predetermined composition and having a specific peak in a powder X-ray diffraction pattern.
