Method for preparing monolayer self-assembling structure of nanorods

The invention relates to a method for preparing monolayer self-assembling structure of nanorods, and in particular relates to a method for preparing a monolayer self-assembling structure of CdSe@Cds nanorods. The method comprises the following steps: smearing a CdSe@Cds nanorod solution onto a copper screen which is wrapped with a carbon film and used for a transmission electron microscopy for observation through a dripping and smearing method; and then performing the self-assembling of the CdSe@Cds nanorods on a carbon film substrate by a thermal annealing technology. Compared with the other self-assembling methods, the self-assembling method in a thermal annealing manner is simple in process and does not require complicated supplementary instruments such as a template and the like, thereby being suitable for large-scale preparation of superlattice structures; and more importantly, the method can be used for partially removing organic insulating molecules wrapping the surfaces of the nanorods so as to improve the electric conductivity of the nanorods. The method has the advantages that the method is novel, simple, low in cost and simple to operate; and the defect in the prior art that the large-scale preparation of the nanorods with self-assembled monolayers is not realized is overcome, so that the method has a good application prospect in the field of nanocrystalline photoelectric devices.
