| Abstract: | The size and morphology of the Cu2O nanocrystals are crucial to improving the performance of photoelectric devices.In this paper,Cu2O nanocrystals have been deposited onto aluminum substrates.The effect of different applied potentials on the chemical composition,morphology and grain size has been investigated.Compared with previous work,it has been found that the potentials have strong effect on particle size,while the morphology changes only when the potentials over-0.5 V,but no other compositions such as CuO or Cu exist in the products,which could clarify the formation mechanism of the Cu2O nanocrystals. |
