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 well.Bismuth 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.
