Abstract
Micro and nanostructures with well-defined shape have attracted great interest due to their novel properties and diverging applications. Herein the one step simple sonochemical method for the synthesis of carambola fruit shaped and spindle shaped semiconducting copper oxide nanostructures are described. The pH concentration and the reaction time have been varied in order to find the optimized condition in which spindle shaped and carambola fruit shaped CuO nanoparticles are obtained. Also the effect of pH and reaction time on the properties of CuO nanostructures have been investigated and reported. The possible growth mechanism for the carambola fruit shaped structures has also been discussed. The prepared samples have been characterized using scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy and UV–visible spectrophotometry.
