Description of Yttrium Gallium Aluminum Garnet (YGaAG) Phosphor Powder
The addition of Gallium in Yttrium Gallium Aluminum shifts the peak emission wavelength to short wavelengths compared with Yttrium Gallium Aluminum phosphor powder, therefore giving the phosphor a stronger green component.
Our LED phosphors can help LCD manufacturers produce displays with high color gamut, giving the screen unprecedented color realism and providing materials that match high-performance color filters. This LED phosphor material range offers outstanding stability and efficiency. This series of phosphors can be used in red LED packages or in combination with other yellow or green phosphors to package warm white or special light LEDs.
