A series of high quality Ni x Mg 1 ‐x O bowl‐shaped array films are successfully prepared by a simple one‐step assembly of polystyrene colloidal spheres and metal oxide precursors at oil–water interface, and further used to fabricate nanodevices. The doping of Mg 2+ can greatly enhance the current and spectrum responsivity of NiO film‐based nanodevice. The maximum R λ value of these bowl‐shaped Ni x Mg 1 ‐x O film‐based devices measured in the study shows 4–5 orders of enhancement than the previously reported Ni x Mg 1 ‐x O film at equal doping.
