China's deposits of rare earth materials account for more than 80% of the world, and Deng Xiaoping, China's chief designer, once said, "The Middle East has oil, China has rare earths." Rare earth ore is a strategic resource for China. Therefore, nano rare earth materials are the future development direction of our business.

The phenomenon of fluorescence is a photoluminescence process. In this process, short-wavelength electromagnetic waves in the ultraviolet or visible wavelength band are absorbed and then released as long-wavelength electromagnetic waves. magnetic waves are absorbed and then released in the form of long-wavelength electromagnetic waves. The latter usually falls in the visible range and is superimposed with The latter usually falls in the visible range and is superimposed on the regular reflected light, thus revealing a dazzling glow color.

Covering powerWhen an object is coated with a certain paint, the ability of the pigment in the paint to cover the base color on the surface of the object to be coated, so that the base color can no longer be revealed through the paint.Covering power = pigment mass (g) / surface area of the object to
