The main applications of rare earth luminescent materials

The use of rare-earth light-emitting materials will bring the effects of environmental protection and energy saving, good color rendering function and long life number to the light source, which is conducive to promoting the upgrading of products in the current significant area. Therefore, once the rare-earth light-emitting materials are created, they are quickly used in the production of color television picture tubes (CRTs) and fluorescent lamps. The industrial use of rare-earth light-emitting materials in China also began in the...
