文摘ZnO nanoparticles with very narrow size distribution were synthesized by coupling homogeneous precipi-tation with microemulsion under pulsed microwave heating. The conditions of preparing ZnO nanoparticles were inves-tigated. The products were characterized with DTA, TGA, XRD, TEM and UV-Vis. The synthesized ZnO nanopartices had much stronger ultraviolet absorptivity than normal ZnO powders; the average size of products was sensitive to the variation of the power or duration of microwave irradiation.
