Abstract

The invention discloses a white light emitting diode and a preparation method thereof. The phosphate glass material is prepared by a high-temperature melting method, wherein the phosphate glass material includes rare earth elements and transition group elements, and the rare earth elements are selected from Eu 3+ 、Sm 3+ 、Dy 3+ or Er 3+ At least one element or combination thereof, the transition group elements are selected from Mn 2+ , Sb 3+ , Pb 2+ or Sn 2+ at least one element or combination thereof. In addition, by performing a heat treatment process on the phosphate glass material, a phosphoric acid glass-ceramic fluorescent material with a single matrix is ​​obtained, so that it can simultaneously emit red light, green light and blue light under the excitation of ultraviolet light.

Description

technical field [0001] The invention belongs to the field of light-emitting diodes, and in particular relates to a white light-emitting diode material and a preparation method thereof. Background technique [0002] In recent years, with the advancement of science and technology, light-emitting diodes have high luminous efficiency, and have the characteristics of energy saving and environmental protection. The user's demand for light emitting diode (LED) lighting is increasing, and the requirements for lighting quality are gradually increasing. At present, it has gradually replaced the traditional light source. Compared with traditional light sources, light-emitting diodes have the advantages of good luminous efficiency, long life, high reliability, unbreakable, power saving, environmental protection, and small size, so their application range is very wide. [0003] Light-emitting diode is a semiconductor component that can emit cold light beams. In white light-emitting diod...
