In the photoluminescence (PL) spectra, we observe the strong evidence that the band gap emission enhancement can be as high as 30 times. In the second part, the NiO-Cu¬¬2O superlattices (SLs) and Cu nanotubes were grown based on AAO membranes. We demonstrate the quantum confinement effect in NiO-Cu2O SLs. Finally, we attempt to transform the Cu nanotubes into Cu2O cactus shape nanotubes by using the combination of AAO template and hotplate methods. |
