2、le 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

3、 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 o

4、rganic 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 dop

5、ing 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

6、 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

7、 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: f

8、irst, 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 energ
