Description of Yttrium-Gallium-Aluminium Garnet (YGaAG) Phosphor Powder
By incorporating Gallium into Yttrium-Gallium-Aluminium, the peak emission wavelength shifts to shorter wavelengths relative to Yttrium-Gallium-Aluminium phosphor powder, thereby increasing the green spectral component.
Our LED phosphors assist LCD manufacturers in producing displays with an extended colour gamut. They ensure that the display meets defined colour accuracy parameters and use materials that are compatible with high-performance colour filters. This LED phosphor series has been characterised by stable output and efficiency that meets industry specifications. The phosphors may be deployed in red LED packages or combined with other yellow or green phosphors for warm white or specialised lighting applications.
