Process for preparing europium oxide doped inorganic lighting material

Abstract

An inorganic luminous material featuring that europium oxide is doped into ThO2 is prepared through proportionally mixing tetrahydrated thorium nitrate with europium oxide, calcining at 400-1000 deg.C for 1-2 hr and cooling.

Description

technical field [0001] The invention relates to a preparation method of a rare earth luminescent material, in particular to a preparation method of a luminescent material doped with europium oxide in thorium dioxide. Background technique [0002] Luminescence is the process by which energy is somehow absorbed inside an object and converted into light radiation. At present, the luminescent materials used include two categories: organic and inorganic, mainly inorganic compounds, and mainly solid materials. From the perspective of morphology, most of them are powder polycrystalline, followed by single crystal and thin film. Among the solid materials, most of them are insulators or semiconductors with large band gaps. The luminescent properties of inorganic materials are related to the structural defects and impurity defects of the compounds. The luminescence caused by the former is called non-activated luminescence (self-activated luminescence); the latter is called activated...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the operation process of the existing method for preparing luminescent materials is relatively cumbersome and the reaction conditions are relatively harsh, and to provide a method for preparing luminescent materials by rare earth doping with simple operation process and mild preparation conditions.
