|Title:||Preparation of ear-like, hexapod and dendritic PbS using cyclic microwave-assisted synthesis|
Physics and Astronomy
|Abstract:||Different morphologies of PbS were prepared using microwave-assisted synthesis of 1:4, 1:1 and 4:1 molar ratios of Pb(CH3COO)2to NH2CSNH2in propylene glycol. Cubic PbS was detected using X-ray diffraction (XRD) and selected area electron diffraction (SAED). Raman spectrometry revealed the presence of vibrations at 134, 274 and 430 cm- 1. The product morphologies for different molar ratios of Pb(CH3COO)2to NH2CSNH2were also characterized using a scanning electron microscope (SEM) and a transmission electron microscope (TEM). The obtained morphologies changed with molar ratios used for the starting agents. The simulated diffraction pattern was also in accordance with the interpretation of the experimental results. © 2008 Elsevier B.V. All rights reserved.|
