Optical and Structural Analysis of Surfactant Assisted Hydrothermal Growth ZnO Nanostructures
Hydrothermally grown ZnO nanostructures have shown high defect level emission and poor adhesivity with the substrate that was highly undesirable for optoelectronic device applications. Therefore, in this work, we have targeted these critical issues by using the surfactant (Na3C6H5O7) in the hydrothermal growth of ZnO nanostructures. Different morphologies of the nanostructures such as nanoplates and honey comb structures have been obtained by varying the surfactant concentration in the precursor solution. This has led to the significant enhancement in the NBE (near band emission) to DLE (deep level emission) ratio in the photoluminescence analysis. These ZnO nanostructures can be potential candidates for the fabrication of next generation optoelectronic devices.
