Silicate Phosphors Description
The green Silicate Phosphor is used for high-power positive white LED packaging, and has the characteristics of good thermal stability, long life, high brightness, uniform particle size, and high conversion efficiency. Moreover, it has a small attenuation for long-term use under high temperature and high humidity atmosphere and can be used for manufacturing an LED lighting device excellent in temperature and humidity resistance.
Our LED phosphors can help LCD manufacturers produce displays with high color gamut, giving the screen unprecedented color realism and providing materials that match high-performance color filters.
This series of Silicate Phosphors can be used in combination with other yellow or red phosphors to package warm white or special light LEDs.

Silicate Phosphors FAQs
Q1: What are Silicate Phosphors?
Silicate phosphors are luminescent materials made from silicate-based compounds doped with activator elements (such as rare earths). These phosphors absorb energy (such as UV or blue light) and re-emit it as visible light, making them essential in display technologies, LED lighting, and other optoelectronic applications.
Q2: What advantages do Silicate Phosphors offer over other phosphors?
Superior Thermal and Chemical Stability: Ideal for high-power LEDs.
Longer Lifespan: More durable compared to organic phosphors.
Eco-Friendly: Free of toxic heavy metals like cadmium.
Broad Range of Colors: Easily tuned by changing activators and doping levels.
Q3: How do Silicate Phosphors contribute to LED efficiency?
Silicate phosphors convert blue LED light into white light, improving the color rendering index (CRI) and luminous efficiency.
Their stability ensures that the brightness and color quality of LEDs are maintained over time.
