Silicate Phosphor Description
The green silicate phosphor is employed in high-performance positive white LED systems. It demonstrates stable thermal behaviour, an extended operational lifespan, high luminous output, uniform particle size, and a high conversion efficiency. In addition, it exhibits low attenuation under prolonged exposure to elevated temperatures and high humidity. Consequently, it is used in LED lighting devices where resistance to variations in temperature and moisture is required.
Our LED phosphor products assist LCD manufacturers in producing displays with an extensive colour gamut. They provide materials that comply with the requirements of high-performance colour filters. Consequently, these silicate phosphor products may be combined with other yellow or red phosphors to produce warm‐white or specialised LED lighting modules.
