Comparison of extra electrons in colloidal n-type Al3+-doped and photochemically reduced ZnO nanocrystals

The "extra" electrons in colloidal n-type ZnO nanocrystals formed by aliovalent doping and photochem. redn. are compared. Whereas the two are similar spectroscopically, they show very different electron-transfer reactivities, attributable to their different charge-compensating cations (Al3+vs. H+).
