摘要：

The surface morphology of amorphous MoO3 films enhanced by a coating of N,N-dimethylformamide was studied with an atomic force microscope. Images of the as-grown films revealed a surface structure consisting of approximately 25 nm diameter clusters which had coalesced to form irregular-shaped grains with dimensions ranging between 100 and 190 nm. Similar structure was found in the films after a photochromic or thermochromic transition had occurred. The relative surface areas of the films have been calculated and little change is observed after the photochromic transition while a approximately 2% increase in surface area is observed after the thermochromic transition has taken place.
