ZYP550N - Oxynitride yellow phosphor for LEDs

The oxynitride yellow phosphor ZYP550N is a product for white LEDs independently developed by our company (patent has been approved). Its structure is different from that of YAG and TAG, and it is best applied to the packaging of white light LED products. Furthermore, its application is not restricted by the international white LEDs patents.

Excitation Wavelength 300-470 nm
Primary Emission 550±1 nm
Dominant Emission 563±1 nm
D50 12.5±1 um
Relative Brightness 105-110
CIE X=0.395±0.005

Type: Oxynitride
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 of highly bright white LEDs of CCT 8000K with blue chips.
Can be used to manufacture warm white LEDs with red phosphors.
Can be used to manufacture high color rendering white LEDs with other phosphors, such as red and/or green 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.
