Synthesis of Well-Aligned ZnO Nanowhisker Films Using Aqueous Solution for Use in Dye-Sensitized Sensor

Abstract:

Highly conductive and well-aligned ZnO nanowhisker films which can be used to optoelectronic devices have been fabricated on conductive F-doped SnO2 coated glass substrates using aqueous solutions with the addition of polyethylenimine at a lower temperature. ZnO nanowhiskers with well crystalline and hexagonal morphology were grown with high orientation along the c-axis. The electrical properties were investigated by a low intensity red laser irradiation (6 mW), after DNA molecules labeled with dye molecules were absorbed on the nanowhiskers. Enhanced photocurrent was detected.
