Manufacturing of ZnO semiconductors from the Zn(CH3COO)2•2H2O precursor via a Polyol-Mediated Thermolysis Process
Resumen
In this work, the instrumentation of a system to manufacture ZnO semiconductors using the Polyol-Mediated Thermolysis Process are reported. The semiconductors manufactured from the Zn(CH3COO)2•2H2O precursor have been synthesized in different molar concentrations (0.001 M, 0.01 M, and 0.1 M), at low temperatures and atmospheric pressure. The structural and morphological characteristics of the ZnO semiconductors were studied by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). XRD has been confirmed the manufacturing of the ZnO semiconductors with high crystalline quality. No other crystalline phases were detected. The SEM micrographs reveal that the morphology of the non-agglomerated quasi-spherical particles (composed of nanometer-sized particles) has been controlled from the agglomerated particles, when the concentration of 0.001 M to 0.01 M is used, respectively. When the highest concentration has been used, no aggregation occurs and only tiny particles in the nanosized range are obtained. As a result, the synthesis route successfully demonstrates the manufacturing of semiconductors in a single step, in a simple-strategy process, being of low cost and scalable to industrial level.
