Synthesis of web-like-structured ZnO cluster with strong photoluminescence intensity
چکیده انگلیسی
A web-like-structured ZnO cluster (WLSZC) has been prepared by applying ultrasonic treatment for 70 min during the co-precipitation process. These samples were subsequently characterized by high-resolution transmission electron microscopy (TEM) and photoluminescence (PL) spectroscopy. In WLSZC, we observed homogeneous polygons, which consist of one single-crystal particle at each side. The PL intensity of the WLSZC is 8-14 times greater than that of nano-particle samples, most likely due to the resonant effect of the polygonal pores (about 100 nm wide). In addition, four blue peaks appeared in the prepared samples indicates that variable defects may be produced during the ultrasonic treatment.
