Abstract Two-dimensional 2D ZnO inverse opal IO films were fabricated by co-assembly of sacrificed polystyrene PS microspheres and citric acid-zinc acetate CA-ZA aqueous solution at an oil–water interface followed by calcination. Their morphologies could be controlled by the surface property of polymer templates and CA-ZA molar ratio. Moreover, photo-detecting devices based on such films were constructed, which showed high photocurrent up to 4.6 μA, excellent spectral selectivity, and reversible response to optical switch.
