ZYP555SG2 - YAG yellow phosphor for LEDs

ZYP555SG2 is a novel yellow phosphor product for white LED independently developed by our company. Due to the fact that its emission peak wavelength is at 555nm, which corresponds to the most sensitive human visual wavelength, it has the highest brightness among all the yellow phosphors. In comparison with other similar products in market, it is best applied to the manufacture of white LED package products, owing to its high brightness, high thermal stability, excellent safety and environmental protection, as well as its small medium particle diameter.

Excitation Wavelength 450-460 nm
Primary Emission 553±1 nm
Dominant Emission 569±1 nm
D50 9±1 um
Relative Brightness 118-120
CIE X=0.431±0.005

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 high bright 6000-7000K (CCT) white LEDs with blue chips.
Can be used to manufacture 2700-4500K (CCT) warm white LEDs with red phosphors.
Can be used to manufacture high color rendering white LEDs with other phosphors.
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.
