Low-temperature growth and properties of CuO structures prepared by aqueous solution process.

The effects of additives on the morphologies of CuO structures have been examined in this study. Two different morphologies of CuO structures, i.e., flower-shaped and ellipsoidal-shaped have been synthesized via a facile and low-cost simple solution method by using two different additive molecules, i.e., hexamethylenetetramine and triethylamine, respectively. From detailed morphological observations, it was concluded that the morphologies of CuO structures are strongly dependant on the use of specific additives molecules and by using a particular additive, a specific CuO structures can be obtained. The synthesized products were examined in detail in terms of their structural properties. The detailed structural characterizations exhibited the nanocrystalline nature with monoclinic structure for the as-synthesized flower-shaped and ellipsoidal-shaped CuO structures.
