| titleOfInvention | Red and green luminescent rare earth up-conversion nanoparticles regulated and controlled by exciting light and preparation method thereof |
| abstract | The invention discloses red and green luminous flux regulated by exciting lightThe soil up-conversion nano particles emit red fluorescence under the excitation of 980nm laser and emit green fluorescence under the excitation of 800nm laser; the nano-particle is of a 4-layer shell-core structure and sequentially comprises an activator layer, an energy transfer agent layer, a sensitizing agent layer and a passivating agent layer from inside to outside, and the chemical expression is as follows: NaErF 4 :Yb,Tm@NaYF 4 :Yb@NaNdF 4 :Yb@NaYF 4 . According to the invention, through adjusting the doping concentrations of different ions in the core-shell structure of the rare earth upconversion nanoparticles, the rare earth upconversion nanoparticles can emit fluorescence of different colors along with the change of the wavelength of exciting light; the rare earth up-conversion nanoparticles prepared by the method have the characteristics of simple preparation, easily obtained raw materials, excellent optical performance and the like, and have wide application prospects. |
