Abstract

The invention discloses a cerium and erbium-doped silicate long-afterglow light-emitting material and a preparation method thereof. The cerium and erbium-doped silicate long-afterglow light-emitting material is mainly a composite-function inorganic fluorescent material formed by 2 alkaline earth metal ions Ba and Mg, 1 transition metal Mn and effective doping of 2 rare earth metal ions Ce and Er. The material has a stable long-afterglow light-emitting performance and relatively high thermal stability. Nominal components of the material are Ba<2+>, (2.00-2.30) Mg<2+>, (2.00-2.30) SiO3<2->, (0.150-0.170) Mn<2+>, (0.0080-0.0098) Ce<2+>, and (0. 0050-0.0080) Er<3+>. The light-emitting material provided by the invention has certain potential to be used in safe, energy-saving and environment-friendly glass products.

Description

technical field [0001] The invention relates to the technical field of material synthesis, in particular to a silicate long-lasting luminescent material doped with cerium and erbium and a preparation method thereof. Background technique [0002] In recent years, compound salt long-lasting luminescent materials formed by the introduction of alkaline earth metal ions and rare earths have attracted great interest and widespread attention. This kind of silicate long-lasting luminescent materials is being developed in more emerging fields. get applied. Not only because the silicate long-lasting luminescent materials have good chemical stability and excellent water resistance, but also mainly because the silicate long-lasting luminescent materials have various luminescent colors, which is conducive to the realization of multi-colored production of long-lasting luminescent colors. They It can exhibit specific long-lasting luminous properties or functions. However, it is very chal...
