Abstract

The invention provides a fluorescence fertilizer for a fixed light source and a preparation method thereof. The fluorescence fertilizer is prepared from Eu2O3, S, Y2O3, La, BaCO3, NH4H2PO4 and BaCl2.2H2O. The preparation method of the fluorescence fertilizer comprises single-phase fluorescence fertilizer preparation, single-phase fluorescence fertilizer grinding and single-phase fluorescence fertilizer thermal-treatment and like steps. In comparison with the fluorescence fertilizer manufactured through a conventional measure, the fluorescence fertilizer prepared by adopting above step is in amicro-particle state; when the fluorescence fertilizer provided by the invention is applied to the fixed light source, the fertilizer can be directly used without being repeatedly grinding; the fluorescence fertilizer of this scheme is high in brightness, and the brightness of the fixed light source is improved.

Description

technical field [0001] The invention relates to a preparation method of a fluorescent material, in particular to a fluorescent material for a fixed light source and a preparation method thereof. Background technique [0002] With the advancement of science and technology, more and more researches have been done on fluorescent materials, and the application range of fluorescent materials has become wider and wider. In addition to being used as dyes, fluorescent materials are also widely used in organic pigments, optical brighteners, photooxidants, coatings, chemical and biochemical analysis, solar collectors, anti-counterfeiting marks, drug tracers, lasers and fixed light sources. Applications. [0003] At present, the fluorescent materials used for fixed light sources are inorganic fluorescent materials, which are generally prepared by a high-temperature solid-phase method, and then the prepared fluorescent materials are screened to separate microparticles, but this method ...
