In the present research, we report the synthesis of ZnO nanoparticles modified by polyvinyl pyrrolidone(PVP). The resulting ZnO has the mean diameter of 4.0 nm with the narrow distribution. It has the same structure phase with bulk ZnO which is synthesized under 450 degreesC, 6 X 10(8) Pa preparation condition. The EXAFS results reveal that with. the decrease of ZnO particle sizes to the nanometer range the coordination number decrease. The interaction between oxygen and Zinc is relatively stronger in these nanosized materials, the, Zn-O bond length is slightly shorter than one in the bulk ZnO indicating a structural contraction for the small nanoparticles.
