Figure 2

Peak intensities and positions as a function of different parameters (i.e. anodization voltage ( V HA ), pore diameter ( d p ), membrane thickness ( τ ) and annealing temperature ( T )) ( λ ex = 350 nm) (red solid lines and circles - oxalic and blue dotted lines and stars - Malonic). (a) and (b) HA-Ox1.1-HA-Ox1.4 and HA-Ml1.1-HA-Ml1.4. (c) and (d) HA-Ox2.1-HA-Ox2.4 and HA-Ml2.1-HA-Ml2.4. (e) and (f) HA-Ox3.1-HA-Ox3.4 and HA-Ml3.1-HA-Ml3.4. (g) and (h) HA-Ox4.1-HA-Ox4.5 and HA-Ml4.1-HA-Ml4.5.
