low priceUniform particle size distributionlow light degradation

Excitation Range :430 to 465 nm

chemical component :rare earth  garnet 

Brief introduction:

The yellow phosphor is a new product independently developed by our company.It is YAG phosphor which has the performance of high brightness and low luminous decay. It is more applicable to the manufacture of high GRI white LED and other white LED

lighting products .It can also realize green LED by using with blue chips.

Primary characters:

Appearance :yellow crystal powder

Chemical component :rare earth garnet

Chemical stability : No decomposability in water , strong stability from -50°C to 300°C in the air

Safety Capability : Meet the RoHS standard, no radiation, no toxicity, no hazard to human, and no pollution to environment.

 

Usages

1) Can be applied to package green LEDs with blue or UV chips.

2) Mixed with yellow phosphors, high color temperature and high CRI can be packaged with blue chips.

3) Mixed with yellow phosphor and red phosphor very high CRI white LEDs can be packaged   with blue chips.

 

Directions

  Weigh phosphors and epoxy or silicone in correct concentration. Mix phosphors and silicone well and pump in vacuum chamber to eliminate air bubbles. Package some LEDs and measure. Adjust concentration and repeat until desired CIE is achieved.  (Can be mixed with other phosphors)

 

Packaging and Storage

Packaging: in a plastic bottle.

Storage conditions: Keep products sealed in packaging and store in a clean and dry environment.
