Additional file 1:

EDX-SEM analysis of ZnO nanowires before the irradiation process. This file displays a SEM image at low magnification showing the initial sample just after growing the nanowires. On the right of the SEM image, an EDX spectrum is presented with a table containing the quantitative analysis and confirming that the composition was very close to the stoichiometric one.

Additional file 2:

Color change detected in ZnO irradiated areas. This file shows samples irradiated with different energies. As can be seen, a clear color change is observed in the irradiated area by the naked eye when illuminating under UV light. The irradiated areas appear black.
