Growth Mechanism and Optical Property of A Novel ZnO Mesoscale Superstructure

摘要：

　　ZnO mesoscale superstructures (ZMS) with the sizes of 2 to 6 μm were synthesized by a simple solution method without any additives.The novel ZMS were assembled by numerous nanoparticles with the diameter of less than 100 nm,and no pores were found.X-ray diffraction shows that the ZMS mainly evolved in solution.The formation process of the ZMS accords to the classical theory of nucleation and growth.Photoluminescence (PL) analysis shows a sharp UV emission peak at 392 nm and a weak broad green-yellow emission peak at about 600 nm.
