Mechanism for the evolution of In2O3 NPs to nanostructured In2O3 films. (a) Cross-sectional FESEM images of In2O3 NPs (i) without and with (ii) 7 and (iii) 10 min of thermal radiation treatment. The magnified FESEM images from the top and bottom layers of the bilayer nanostructured polycrystalline In2O3 films in (ii) are shown on the right-hand side of (ii). (b) Schematic of the structure deformation of the In2O3 NPs (i) into the nanostructured In2O3 films (ii, iii) upon thermal radiation treatment.
