ZYP640G3 - Low luminous decay nitride red phosphor for LEDs
ZYP640G3 is a new oxynitride red phosphor that is independently developed by our company (patents have been approved). 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 packaged products. The products can also be applied to the packaging of red LED with blue or UV chips.
| Excitation Wavelength | 300-470 nm |
| Primary Emission | 640±1 nm |
| Dominant Emission | 607±1 nm |
| D50 | 7±1 um |
| Relative Brightness | 90-95 |
| CIE | X=0.660±0.003 Y=0.339±0.003 |
| Type: | Nitride |
| Appearance: | Red 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 the mixture of ZYP640G3 and yellow phosphor, 2500k-4000K warm white LEDs can be realized, with CRI of the packaging products reaching over 80. Using the mixture of ZYP640G3, yellow phosphor and/or green phosphor, cool white LEDs and warm white LEDs can be realized, with CRI of the packaging products reaching over 90. Red 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. |
