The SEM and AFM images of three TiO₂ nano-films prepared at different conditions were obtained and transformed into digital format.The multifractal analyses for three films were made using height from a depth of thickness of film B and q from 55 to-55.The scale-invariance is very good for all lnχ_q(ε)~lnε plots and τ(q)~q plots at least close to three orders of magnitude.But the multifractal spectra f(a) of the films are quite distinct due to their different height distribution.
