Luminescent material and preparation method thereof |
摘要 |
The formula of a luminescent material is NaY1-xLnxGeO4, wherein Ln is lanthanon, and the value of x is 0<x≦0.2. The luminescent material adulterated with lanthanon constitutes germanate luminescent material comprising lanthanon, which improves efficiently the stability and luminescent performance of the luminescent material. The presence of lanthanon enables the luminescent material to emit light with different colors such as red, green, blue, etc. under the excitation of cathode rays, and be better used in a filed emission device. In the preparation method of the luminescent material, source components are mixed up and directly and sintered, and the luminescent material is acquired. |
