During the development of transparent electrochromic devices, which are based on electrochemical deposition of Ag nanoparticles on ITO substrates and available for exhibiting reversible changes in their optical condition (transparent, black, and mirror) and in their color indication (Y, M, C and R, B), a new green color indication could be achieved with Ag nanoparticles formed by a pulse width modulation (PWM) voltage and solvent selection.
