ZYP615 - Low luminous decay oxynitride red phosphor for LEDs







ZYP615 is a special low luminous decay red phosphor that is independently developed by our company. Compared with other similar products in the market, it has the characteristics of high brightness, high thermal stability, low luminous decay, and excellent safety and environmental protection. It is best applied to the packaging of high CRI or low color temperature white light LED package products. The products can also be applied to the packaging of pink LED with blue or UV chips.


Excitation Wavelength 300-470 nm
Primary Emission 616±2 nm
Dominant Emission 598±1 nm
D50 7±1 um
Relative Brightness 165-175
CIE X=0.620±0.003
Y=0.379±0.003



Type: Oxynitride
Appearance: Orange crystal powder.
Component: Oxynitride chemical compound.
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: Using a mixture of ZYP615 and yellow phosphor, CRI of the packaging products can reach over 80.
Using a mixture of ZYP615, yellow phosphor and/or green phosphor, cool white LEDs and warm white LEDs can be realized, with CRI of the package products reaching over 90.
Pink LEDs can be packaged with blue or UV 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).
Packaging: 50g/bottle.
Storage: Keep products sealed in packaging and store in a clean and dry environment. Avoid long term exposure to air.
