ZYP550G3 - YAG yellow phosphor for LEDs







ZYP550G3 is a special yellow phosphor product that is developed based on the improved technology of ZYP550 phosphor for high power white LED package. It is independently developed by our company with an approved patent. Compared to ZYP550, its medium particle diameter is approximately 15??1??m, and its brightness is increased by nearly 10%. Therefore, it is best applied to the manufacture of high power white LED package.


Excitation Wavelength 450-460 nm
Primary Emission 551±1 nm
Dominant Emission 567±1 nm
D50 15±1 um
Relative Brightness 122-126
CIE X=0.426±0.003
Y=0.548±0.003



Type: YAG
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 packaging highly bright 8000-9000K (CCT) white LEDs with blue chips.
Can be used to manufacture 2700-4500K (CCT) warm white LEDs with red phosphors (ZYP630G3 or ZYP615).
Can be used to manufacture high color rendering white LEDs (CRI>85) with other phosphors such as red phosphor and/or green phosphor.
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.
