| titleOfInvention | The nanocrystalline method of the five fluorine yttrium potassium that are co-doped with using waste phosphor powder synthesizing rare-earth metal |
| abstract | The invention discloses a kind of nanocrystalline method of the five fluorine yttrium potassium that are co-doped with of utilization waste phosphor powder synthesizing rare-earth metal, rare earth ion, potassium bifluoride, potassium hydroxide heating are dispersed in oleic acid, form homogeneous solution, after mixing under hot conditions, react, the five fluorine yttrium potassium that generation ytterbium, europium, erbium are co-doped with are nanocrystalline, by controlling factor grain-size size and the visual intensities such as the ratios of additive such as rear-earth-doped ionic species concentration, potassium resource, Fluorine source and oleic acid, it is achieved that ultraviolet light and near infrared light are to the conversion of multi-wavelength's visible ray.The pattern of products therefrom of the present invention is homogeneous, size is controlled, and luminous intensity is high, can be applicable to the fields such as opto-electronic device, electric source lighting, solar cell and biological fluorescent labelling.Its preparation technology is simple to operate, without the need for special installation, low cost and environmental protection, it is adaptable to the preparation of multiple rare earth up-conversion luminescence nanometer crystals and large-scale industrial production. |
