铋离子掺杂红外发光材料综述

摘要

铋离子红外发光具有良好的应用 前景，

铋是天然放射性元素，

为

有银白 色光泽的金属，质脆易粉碎；室温下，铋不与氧气或水反应，

在空气中稳定，加热到熔点 以上时能燃烧，发出淡蓝色的火焰，生成

三氧化二铋，铋在红热时与空气作用，也可与硫 、卤素化合。而发光

是物体将某种方式吸收的能量转化为光辐射的过程，

而红外发光是某

一段波长的光波吸收能量转换为光辐射的过程。

近红外有机发光材料

主要集中在两大类：一是稀土元素配合物；二是有机离子染 料。远红

外线是红外线中的一种，

远红外线有较强的渗透力和辐 射力，

具有显

著的温控效应和共振效应，

它易被物体吸收并转化为物体的内能。

本

文章就铋离子掺杂红 外发光材料的机理以及影响因素做出理论解释，

并就铋离子掺杂红外发光材料的前景进行 展望。

Review on Bi-doped infra-luminescence materials

Abstract

Bismuth ions infrared glow light has good of application prospects,

bismuth is natural radioactive elements, for metal with silver luster, very

brittle shatter easily; At room temperature, bismuth does not react with

oxygen or water, stable in the air, heated to melting point above can burn,

a light blue flame, and generate the bismuth oxide bismuth in red with the

air, also can compound with sulfur and halogen. And luminous objects is

to absorb the way energy is converted to optical radiation, the process of

the infrared light is a Duan Bo long wavelengths absorbed energy is

converted to optical radiation process. Nir organic light-emitting

materials are mainly concentrated in two categories: one is the rare earth

complexes; Second, the organic dye ions. Far infrared ray is one of the

infrared, far infrared ray has strong penetration and radial force, has a

significant effect, temperature effect and resonance, it is easy to absorbed

by the object and translated into the internal energy of the object. This

article is bismuth ions doping mechanism and affecting factors of the

infrared light emitting materials to make theoretical explanation, and

bismuth ions doped future infrared light-emitting materials is prospected

as h ion infrared glow has good of application prospects,

bismuth is natural radioactive element, for has silver gloss of metal, mass

crisp easy crushed; at room temperature Xia, bismuth not and oxygen or

water reaction, in air in the stability, heating to melting point above Shi

can burning, issued light blue of flame, generated three oxidation II

bismuth, bismuth in red hot Shi and air role, also can and sulfur, and

halogen combined. , Shiny object somehow absorbed radiation energy

into light, and infrared light is a wavelength of light energy converted to

optical radiation absorption process. Near infra-red organic light- emitting

materials are mainly concentrated in two broad categories: first, the

complexes of rare earth elements; the second, organic Ionic dyes. Far

infrared is a form of infrared, far infrared rays with strong penetration and

radiation, with significant temperature effects and resonance effects, it is

absorbed by the body and transform into objects of internal energy. The

article bismuth-doped infrared light emitting materials to theoretical

explanations of the mechanism and influencing factors and prospect

prospect of bismuth ions-doped infrared light emitting material.
