Abstract

The invention discloses a natural albite luminescent material doped with rare earth ions and a preparation method and application of the material. The luminescent material is prepared by adopting a natural albite mineral without any modification treatment as a substrate and making the rare earth ions permeate into crystal lattices of the natural albite mineral by means of a suspension liquid combustion method, wherein the mole ratio of the rare earth ions to the natural albite mineral is (0.001-0.15):1. According to the natural albite luminescent material, the natural albite is used as the substrate, the cost is reduced, and meanwhile the added value of the natural mineral is increased; the preparation method is simple in process, low in energy consumption and suitable for industrial production and application; the luminescent material prepared by means of the method is irradiated by an ultraviolet lamp to emit strong green light and can be widely applied to the field of optics.

Description

technical field [0001] The invention relates to the technical field of mineral functional materials and rare earth luminescent materials, in particular to a natural albite luminescent material doped with rare earth ions and its preparation method and application. Background technique [0002] In recent years, light-emitting diodes (LEDs), solid-state lighting sources, have attracted widespread attention from all over the world due to their advantages such as long service life, high efficiency, energy saving, environmental protection and pollution-free. At present, the main way to obtain white light is to combine LED chips and phosphors, and use LED chips to excite phosphors to mix to form white light. The specific method is as follows: (1) blue LED excites phosphor powder emitting yellow light; (2) near ultraviolet LED excites red, green and blue phosphors. Since the phosphor powder excited by the blue light chip needs to absorb visible light with a wavelength of 420-470nm,...
