ABSTRACT
Long lasting colored pattern formation on sol–gel deposited vanadium pentoxide (V2O5) thin films is demonstrated by atomic force microscope (AFM) nanolithography. The films can be locally colorized by application of a positive dc bias voltage on the conductive AFM tip. The patterns can be erased, or “bleached,” by application of a negative bias voltage. The changes in optical reflectivity, topography, and conductivity measurements made on as-deposited, colored, and bleached areas were consistent with a model in which the incorporation of hydrogen ions into V2O5 thin films is responsible for the coloration process.

    Thin films of hydrated vanadium pentoxide (V2O5 · nH2O) exhibit the phenomenon of electrochromism, whereby a film reversibly changes its color under the action of an applied electric field. A specific feature of this phenomenon is that it takes place in a “dry” planar system, in...
