ZYP570N - Oxynitride yellow phosphor for LEDs







ZYP570N is a novel oxynitride yellow phosphor product for white LEDs that is independently developed by our company (patent has been approved). The structure is different from that of YAG and TAG, and it is applied to the packaging of white light LED products. Furthermore, its application is not restricted by the international white LEDs patents.

Primary Emission 565±1 nm
Dominant Emission 572±1 nm
D50 12.5±1 um
Relative Brightness 105-110
CIE X=0.460±0.003
Y=0.530±0.003



Type: Oxynitride
Appearance: Yellow crystal powder.
Component: Rare earth oxynitride.
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 white LEDs of CCT 3500K-4000K with blue chips.
Can be used to manufacture higher color temperature and high CRI white LEDs with green phosphors.
Can be used to manufacture higher color temperature and high CRI white LEDs with green phosphors.? Can be used to manufacture high CRI white LEDs with green and red 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.
