A study on synthesis and optoelectronic properties of high crystal quality p-type ZnO one-dimensional micro-and nanostructures is key to fabeication and applications of ZnO-based optoelectronic devices. On the basis of unique properties of NaCl nonaqueous ionic liquid and Na in doping ZnO, In this project, our aim is to prepare high crystal quality p-type ZnO noe-dimensional micro- and nanostructures with enhanced optoelectronic properties via a novel and new NaCl nonaqueous ionic liquid method. We will investigate the growth mechanism of ZnO micro- and nanostructures grown in NaCl nonaqueous ionic liquid to control the morphology and size of p-type ZnO one-dimensional micro- and nanostructures. The effect of experimental conditions on the growth of ZnO micro- and nanostructures in NaCl nonaqueous ionic liquid will be investigated to control the efficiency of Na doping ZnO one-dimensional micro- and nanostructures and the concentration of Na in ZnO one-dimensional micro- and nanostructures. In order to understand the physical mechanism of p-type ZnO one-dimensional micro- and nanostructures induced by Na-doping process, the optoelectronic properties of an individual ZnO one-dimensional micro- and nanostructure will be investigated in detail. The results will offer useful experimental and theory basis for the synthesis of high crystal quality p-type ZnO one-dimensional micro- and nanostructures. In addition, the obtained results can also be useful for the fabrication and applications of ZnO-based optoelectronic devices such as light-emitting diodes and laser diodes.
