| Research Abstract |
Environmentally friendly soft solution synthesis of ZnO thin films with precisely developed microstructure and novel functionality were investigated. Homogeneous ZnO thin films consisted of various unique microstructures, such as nanorods, nanonuts, nanospheres, nanodisks, nanoscrews, hollow structure and nanoflowers were successfully synthesis by precisely controlling the reaction conditions. The particle size, aspect ratio and specific surface area could be precisely controlled. ZnO particle thin films with some novel functions, such as conductivity related to transition metal doping, superhydrophobicity, superhydrophilicity, photoluminescence properties, improved photocatalytic activity and high sensitive humidity sensor property related to their unique morphologies were confirmed.
