CIE X=0.413±0.005
Y=0.556±0.005



Type: LuAG
Appearance: Yellow crystal powder.
Component: Rare earth garnet.
Stability: No decomposability in water, strong stability from -50C to 300C in air.
Safety: Meets RoHS standards, contains no radiation, no toxicity. Poses no hazard to humans or the environment.
Usage: Can be applied to package green LEDs with blue or UV chips.
Mixed with yellow phosphors, high color temperature and high CRI can be packaged with blue chips.
Mixed with yellow phosphor and/or red phosphor very high CRI white LEDs can be packaged with blue chips.
Directions: Weigh the phosphor and epoxy or silicone in the correct concentration, and mix them evenly. Pump in the vacuum chamber to eliminate air bubbles before package in LEDs for testing. Adjust the concentration as needed and repeat the above steps until the desired CIE is achieved (it can also be mixed with other phosphors).
