The invention discloses a kind of methods preparing 10 nanometers or less extra small long-persistence nano particles.The preparation method, as presoma, using solution such as amine or alcohol as solvent, can be carried out synthetic reaction under lower reaction temperature, prepare 10 nanometers of grain size extra small long-persistence nano particle below using metal acetylacetonate salt.Material and facility used in the present invention is cheap, and synthesis temperature is relatively low, can significantly reduce at low cost, and preparation process is simple, is suitble to large-scale production.Long-persistence nano particle produced by the present invention has excellent long-persistence luminous property and 10 nanometers of super-smalls below, is detected in biomedical imaging and the fields such as optics is shown have potential application. |
