摘要：

A facile and feasible method for preparing transmission electron microscope (TEM) specimen was reported by combining the phase transfer of aqueous nanocrystals(NCs) and the formation of polymer-supported free-standing films on water/air interface. In comparison to traditional TEM specimen preparation method-especially for aqueous systems, the quality of TEM images is greatly improved due to better particle dispersion. The TEM images show that through optimizing a few preparation factors, distinct particle dispersion and clear images of individual particles cart be observed. In addition, we apply this strategy to other NCs to prove that this method is universal for preparing TEM. samples of various NCs, such as Au, Ag, CdS and CdTe.
