In recent years, considerable attention has been given to both the theoretical and the experimental investigation of the physical and physico-chemical properties of the chromogenics materials due their favorable and promising applications such as electrochromic devices, energy-efficient smart windows, automobile mirrors and building glazings. Electrochromic MnO{sub x} thin films were prepared by using an electron beam technique followed by annealing post-treatment. Electrochromic properties of the films were studied in three different solutions: 1M LiClO{sub 4} in propylene carbonate, KOH (pH = 10.5) and natrium borate (pH = 9.2). The transmittance spectra of the colored films combined with their cyclic voltammograms have showed that the enhancement of the electrochromic behavior of these films can be attributed to the insertion (or extraction) of the OH{sup {minus}} anions into (or from) the MnO{sub x} films. The best electrochromic efficiency of the films was obtained in the borate electrolyte.
