We have synthesized highly monodisperse wurtzite ZnO nanoparticles using poly(vinylpyrrolidone) (PVP) as the capping molecules. The effect of surface modification on size, structure, morphology, and optical properties was investigated. It found that many could be optimized by simply varying molar ratio Zn(II)/PVP. prepared under optimum conditions are particularly stable, monodisperse, well small in size. EXAFS result showed a structural contraction relative to bulk. These exhibit distinct...
