We developed a sol-gel method using photo-induced desorption for size-controlled ZnO quantum dots (QDs). This method successfully controlled the size and size variance of ZnO QDs, and size fluctuations decreased from 23% to 18% depending on the illuminated light intensity. The sol-gel synthesis effectively reduced the number of defect levels that originated from oxygen defects.
我们开发了一种使用光致解吸的溶胶-凝胶法来控制 ZnO 量子点 (QDs) 的尺寸。该方法成功地控制了 ZnO QDs 的尺寸和尺寸变化,并且尺寸波动从 23%降低到 18%,这取决于照射光的强度。溶胶-凝胶合成有效地减少了源于氧缺陷的缺陷能级数量。
