Abstract

original image

Reversible electro-optical switching is achieved in a facile manner by dispersing a small amount of ZnS nanoparticles into blue phase I (BPI). The hysteresis is so small that it can be considered as hysteresis-free at a 0.5–0.7 wt% doping level, and the on-state voltage is much lower than that of polymer-stabilized BPI.
