  • Abstract
    Single-domain VO2 nanocrystals in a fused silica matrix exhibit an extremely large thermally and/or optically induced hysteresis around room temperature. We demonstrate optical imprinting of persistent diffraction gratings and repetitive (> 104) cycling through the phase transition.
