Abstract
The "extra" electrons in colloidal n-type ZnO nanocrystals formed by aliovalent doping and photochemical reduction are compared. Whereas the two are similar spectroscopically, they show very different electron-transfer reactivities, attributable to their different charge-compensating cations (Al(3+)vs. H(+)).
摘要
通过等价掺杂和光化学还原形成的胶体 n 型 ZnO 纳米晶体中的“额外”电子进行了比较。虽然这两种电子在光谱上相似，但它们表现出非常不同的电子转移反应活性，这归因于它们不同的电荷补偿阳离子（Al(3+)对 H(+)）。
