Template-Preparation and Characterization of Semiconductor Nanorod Organosols

摘要

The template method was used to prepare organosols composed of either CdS nanords (diameter = 45 nm or 90 nm) or ZnO nanorods (diameter = 90 nm). Polycarbonate track-etched filters were used as the template membranes. After template synthesis, the nanorods were released from the template membrane and dispersed in chloroform. The stability of these nanorod organosols was monitored using UV-visible absorption spectroscopy. The 90 nm-diameter CdS nanorod organosols were found to be more stable than the 90 nm-diameter ZnO nanorod organosols. In addition, the 45 nm-diameter CdS organosols were found to be more stable than the larger 90 nm-diameter CdS sols. The nanorods that comprise these sols were characterized by electron microscopy, energy dispersive spectroscopy, electron diffraction and powder X-ray diffraction.
