ZYP540 - Yellow phosphor for LEDs

The yellow phosphor ZYP540 is a new product independently developed by our company. It is a YAG phosphor that has the characteristics of high brightness and low luminous decay. It is best applied to the manufacture of high CRI white LED, and other white LED lighting products. It can also be used to realize green LED by coupling with blue chips.

Excitation Wavelength 300-470 nm
Primary Emission 540±1 nm
Dominant Emission 567±1 nm
D50 9±1 um
Relative Brightness 120-120
CIE X=0.413±0.005

Type: LuAG
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 package green LEDs with blue or UV chips.
Mixed with yellow phosphors, high color temperature and high CRI can be packaged with blue chips.
Mixed with yellow phosphor and/or red phosphor very high CRI white LEDs can be packaged with 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).
Packaging: 100g/bottle.
Storage: Keep products sealed in packaging and store in a clean and dry environment. Avoid long term exposure to air.
