ZYP520 - LuAG yellowish green phosphor for LEDs







The yellowish green phosphor ZYP520 is a new product independently developed by our company. It is a LuAG phosphor that has the characteristics of narrow particle size distribution, core-shell structure with spherical morphology, high brightness, and low luminous decay. It is best applied to the manufacture of high CRI white LED package and other white LED lighting products. It can also be used to realize yellowish green LEDs by coupling with blue chips.


Excitation Wavelength 450-460 nm
Primary Emission 520±1 nm
Dominant Emission 533±1 nm
D50 15±1 um
Relative Brightness 114-120
CIE X=0.332±0.003
Y=0.582±0.003



Type: LuAG
Appearance: Yellowish green 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 yellowish green LEDs with blue or UV chips.
Mixed with yellow phosphors, high color temperature and high CRI white LEDs can be packaged with blue chips.
Mixed with yellow phosphors and/or red phosphors, very high CRI (>90) 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).
Packaging: 100g/bottle.
Storage: Keep products sealed in packaging and store in a clean and dry environment. Avoid long term exposure to air.
