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 t
