Silicate Phosphor Powder Description
The silicate phosphor comprises green, yellow and orange variants. Green silicate phosphor is primarily used for packaging white and green LEDs with a high colour rendering index; yellow silicate phosphor is mainly applied in small LED housings for backlighting; orange silicate phosphor is chiefly used in warm white LED housings.
Properties:
- High efficiency, >96%
- Wide range of colours: green, yellow, orange, 505–590 nm
- Narrow emission peak, 70–82 nm FWHM
- Broad excitation range, UV-violet to blue
