Facile Synthesis of a Hierarchical PbTe Flower-like Nanostructure and Its Shape Evolution Process Guided by a Kinetically Controlled Regime

摘要

The architectural manipulation of nanobuilding blocks with well-defined shapes and accurately tunable sizes remains the focus in modern colloids and materials chemistry and is a key for the success of'bottom-up'approaches toward future nanodevice fabrication.Thus,considerable efforts have been devoted to exploit powerful synthetic schemes which allow kinetically or thermodynamically controlling the fabrication of various nanocrystals,and remarkable progress has been achieved,Recently,the formation of complex three-dimensional(3D)nanostructures has attracted more and more attention in the synthetic chemistry and materials area,which is relatively undeveloped,especially in mild and low-cost synthetic routes.
