Comparison of extra electrons in colloidal n-type Al(3+)-doped and photochemically reduced ZnO nanocrystals.
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(+)).
