Abstract
PbO nanorods were synthesized by oxidation of lead sheets under an oxygen ambiance with different temperatures at 330, 400, 450 and 550°C in a tube furnace. Scanning electron microscope (SEM) results showed that the nanorods started growing on the sheet that was placed at 330°C. On the other hand, by increasing of the temperature to 550°C more nanorods appeared on the Pb sheet, which were lied on the lead sheet. X-ray diffraction pattern (XRD) indicated that the nanorods had α-PbO structures. However, a few β-PbO phases also appeared for the nanorods. Raman measurements confirmed the XRD results and indicated two Raman active modes that belonged to α-PbO phase for the nanorods. In addition, the Raman spectrum of the nanorods showed a weak peak of the β-PbO structure. The optical properties of the products were characterized using a room temperature photoluminescence (PL) technique. The PL result indicated a band gap for the PbO nanorods in the visible region.
