                      pentoxide (V2O5) thin films and its optical properties in
                      the near‐infrared (near‐IR) region. Samples were
                      prepared via direct current magnetron sputter deposition and
                      cyclic voltammetry was used to characterize the insertion
                      and extraction behavior of protons in V2O5 in a
                      trifluoroacetic acid containing electrolyte. With the same
                      setup chronopotentiometry was done to intercalate a
                      well‐defined number of protons in the HxV2O5 system in the
                      range of x=0 and x=1. These films were characterized with
                      optical reflectometry in the near‐IR region (between 700
                      and 1700 nm wavelength) and the refractive index n and
                      extinction coefficient k were determined using Cauchy’s
                      dispersion model. The results show a clear correlation
                      between proton concentration and n and k.},
