I'm working on the UV sensor project. I don't know which one to choose? ZnO nanowire or nanorod? Some papers show if the diameter of ZnO be smaller, smaller surface energy will be. So, for UV sensor, choosing NW will be bstter?
First of all please do the SEM to ensure your surface morphology and also do the surface area studies. The surface area study will firmly help you to understand which type of the synthesized particles will have the higher surface area. From my side surface area study will defiantly give you a precise idea on the materials which you want to apply.
Dear Zhou Qian thanks for asking this very interesting technical question. According to some leading references in this field, both ZnO nanowires and nanorods can be employed for the fabrication of ultraviolet (UV) photosensors. For example, please have a look at the following highly useful articles:
UV sensing properties of ZnO nanowires/nanorods
Article UV sensing properties of ZnO nanowires/nanorods
