| titleOfInvention | Lanthanum-doped ZnO quantum dots with high fluorescent quantum yield, and preparation method and application thereof |
| abstract | The invention discloses lanthanum-doped ZnO quantum dots, and a preparation method and an application thereof. The lanthanum-doped ZnO quantum dots are prepared under atmospheric conditions and are uniformly dispersed. The molar ratio of zinc and lanthanum is 100 : 5-50. The preparation method comprises the following steps: firstly, preparing a lanthanum-containing zinc acetate-ethanol solution and a lithium hydroxide-ethanol solution; then mixing the two solutions in ice-water bath, and reacting to form an ethanol solution of the lanthanum-doped ZnO quantum dots; and finally adding deionized water into the obtained solution, centrifuging the solution to separate, removing supernatant, washing repeatedly with anhydrous ethanol and deionized water, and vacuum drying, so that the lanthanum-doped ZnO quantum dots are obtained. The preparation is simple in operation and low in cost, and is helpful to realize industrialized production. The lanthanum-doped ZnO quantum dots have relatively high fluorescent intensity and high fluorescent quantum yield, can be used as additives dispersed uniformly in transparent matrixes to prepare high-end anti-counterfeiting products such as anti-counterfeiting inks, anti-counterfeiting labels, anti-counterfeiting packaging materials, and the like, or can be used for preparing photochromic films or electrochromic nanocomposite films, and can be used for backlights, displays, etc. |
