| titleOfInvention | Preparation method and application of rare earth doped potassium fluoride bismuth potassium luminescent nanomaterial |
| abstract | The present disclosure belongs to the field of rare earth doped luminescent materials, and specifically provides a preparation method and application of a rare earth doped potassium fluoride bismuth potassium luminescent nanomaterial. The basic composition of the luminescent nanomaterial is K 0.3 Bi 0.7‑x‑y F 2.4 : xYb, yLn, wherein Ln 3+ is one of Er 3+ , Tm 3+ , Ho 3+ , 0≤x≤0.30, 0 ≤y≤0.05, or K 0.3 Bi 0.7‑z‑t F 2.4 :zM,tN, where M and N are Ce 3+ , Pr 3+ , Nd 3+ , Sm 3+ , Gd 3+ , Eu 3+ , Tb 3+ , one or both of Dy 3+ , 0≤z<0.35, 0≤t<0.35. The preparation method includes the following steps: adding a Bi-containing compound and a rare-earth element-containing compound into a dilute hydrochloric acid solution, stirring and dissolving at room temperature to 90° C. to prepare a solution A; adding potassium fluoride into deionized water, and at room temperature to 90° C. Stir and dissolve at 90°C to prepare solution B; add solution A to solution B and stir at room temperature to 90°C. After the reaction is completed, the obtained precipitate is centrifuged and washed with distilled water. The invention solves the problems in the prior art that the bismuth-containing rare earth-doped light-emitting nanomaterial is synthesized at low temperature and the stability is poor and the bismuth-containing rare-earth-doped light-emitting nanomaterial is rapidly synthesized in an aqueous solution. |
