Anodic luminescence is correlated to the existence of morphological defects in the oxide.

Spectrum under spark discharging reveals only oxygen and hydrogen lines.

Oxide films formed under spark discharging are crystallized and composed of Nb2O5.

Photocatalytic activity and photoluminescence of Nb2O5 films increase with time.
