Abstract

Bis(8 hydroxyquinoline) nickel nanoribbons with average width of 1 0 0 nm and thickness of 2 0 nm and length up to tens of micrometers have been synthesized via a facile solvothermal method. A photoswitch was fabricated based on bis(8 hydroxyquinoline) nickel nanoribbons and t he nanoribbons were found to be sensitive to light. As the light source was switched on and off, the currents could be reversibly switched between high and low value at the voltage of 0.01 V. The photocurrent enhanced by ca. 8.7 times under irradiation of an incandescence lamp compared to in the dark. This conclusion was interesting and might be found potential application in light controlled devi ces in the future..
