Title Effect of Interfacial Properties on Properties of Zirconia Photodetector

Abstract：Zirconia nanocrystals have potential applications in many fields such as the manufacture and improvement of optical devices, electrochemical capacitance electrodes, oxygen sensors, fuels, catalysts (including photocatalysis) and new ceramic materials. In this paper, zirconia nanocrystals were synthesized by oil phase pyrolysis and photodetectors were prepared by spin coating and graphene silicon wafers. The photoluminescence properties and UV response characteristics were studied. The effects of zirconia nanocrystals Structure and morphology, interfacial impurities, defects and so on on its charge transport and photoelectric conversion performance. In this paper, the microstructure and morphology and defects of zirconia nanocrystals were analyzed by TEM and photoluminescence. The photocatalytic performance of the composite photodetector was analyzed by the IV characteristic curve and the UV response. Obtain the final conclusion based on the data representation results.
