Size control of sol–gel-synthesized ZnO quantum dots using photo-induced desorption
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 effe...

Zusammenfassung: | 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. |
