What types of LED phosphors were used in the market in 20 13 years?

Of course, YAG phosphor is the most widely used in LED market, far more than other kinds of phosphors. It has high brightness, stability and cheapness, and can be used for backlight and lighting. It can be used to wrap light beads with low refractive index with single powder and light beads with high refractive index with red powder. The main specifications of YAG are YAG: Ce and Lu-doped YAG: Ce, and the peak wavelength distribution can be controlled at 520~580nm by changing the group.

Secondly, silicate phosphors have the advantages of avoiding Japanese patents, narrow peak, good color saturation and high brightness, and are widely used in medium power packaging of backlight.

In addition, there is red nitride powder, the wavelength is generally 620~680nm, which is used for high index packaging. Divided into 258 components and 1 1 13 components, the consumption has increased rapidly in the past two years.

Other phosphors include TAG and the like. The commercial phosphors with great potential in the future are quantum dots and nitride green powder.
