Abstract
The copper oxide (CuO) nanoneedles were synthesized by a simple hydrothermal method. Field emission scanning electron microscopy revealed the formation of high-density CuO nanoneedles with ultrathin nanotip at low temperature. The X-ray diffraction (XRD) results showed that the CuO nanoneedles have monoclinic structure with single crystalline phase. High-resolution transmission electron microscopy (HRTEM) and selected area electron diffraction results also assisted the products single crystalline nature. The magnetic properties of CuO nanoneedles were studied using a superconductor quantum interference device (SQUID) magnetometer, and revealing a ferromagnetic behavior of the CuO nanoneedles. The coercivity of CuO nanoneedles at 3 K was estimated to be 42 Oe. These CuO nanoneedles may be implicated to various applications such as drug delivery, magnetic resonance imaging and field emission devices.
