Figure 1
Photoluminescence spectra as a function of different parameters (i.e. anodization voltage ( V HA ), pore diameter ( d p ), membrane thickness ( τ ) and annealing temperature ( T )) for NAAMs fabricated in oxalic and malonic acids ( λ ex = 350 nm-Black arrows indicate the evolution of the PL peak maxima when the corresponding experimental parameter is modified).
