An electrochromic cell has been paid attention to the possible application. Here, we like to report our fabrication of the electrochromic cell with methyl viologen and Prussian blue as a electrochromic materials and GQD as a supporting electrolyte. This is the first trial to use GQD as a electrolyte. The switching property of methyl viologen was recorded from the transmittance changing at λmax (550nm) for 1000 s. The coloration of methyl viologen was very reversible by applied potentials. The value of transmittance change (Δ T) is around 39 %, which is the best result what we have achieved. Moreover, in terms of stability that is one of the best fittable applications for a carbon based materials with GQD, our study is obviously valuable. And the heat stability test was done by chronoamperometry with GQD compared to the KCl cell. After heating the cell, the chronoamperometric response is more stable and reversible than that of KCl cell. Applying GQDs as an electrolyte is expected to be a novel separator between two electrodes and allows to give an easy processing for the device fabication. We believe that these new results should open up new possibility of carbon based industry.
