Paper Abstract

Electrochromic MnOx 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: ll1 LiC104 in propylene carbonate, KOH (pH= 10.5 ) and natrium borate ( pH= 9.2 )_ The transmittance spectra of the coloured films combained with their cyclic voltammograms have showed that the enhancement of the electrochromic behaviour of these films can be attributed to the insertion (or extraction) of the OH- anions into (or from) the MnOx films. The best electrochromic efficiency of the films was obtained in the borate electrolyte.
