ZYP540NH - Oxynitride green phosphor for LEDs
ZYP540NH is a novel oxynitride green phosphor for LEDs independently developed by our company. In comparison with other similar products in the market, it is best applied to the manufacture of LED package products with UV and blue chips, owing to its high brightness, high thermal stability, low luminous decay and excellent safety and environmental protection features.
|Excitation Wavelength||300-470 nm|
|Primary Emission||538±1 nm|
|Dominant Emission||555±1 nm|
|Appearance:||Green crystal powder.|
|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 used to manufacture high CRI white LED (>90) by mixing ZYP540NH with red or yellow phosphor in a specific proportion.|
Can be used to package aqua LEDs with blue LED chips; it is best used with UV or short wavelength 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).|
|Storage:||Keep products sealed in packaging and store in a clean and dry environment. Avoid long term exposure to air.|
