Paper Abstract

A novel but simple high contrast optical switching suitable for display! window applications is demonstrated. The technique is based on electrochromic effect in electrochemically prepared prussian blue (PB) film. The switching action is observed through a colour change from dark blue to total trans prency by simultaneous insertion of K ions and electrons into prussian blue lattice. The device performance and its improvement over the presently known state of the art technology using prussian blue films are also briefly discussed. 1.
