摘要：

The polyether-grafted ZnO nanoparticles with tunable and stable photoluminescence at room temperature were prepared by modifying the conventional sol-gel technique. The quantum yields of the ZnO-poly(ethylene glycol) methyl ether (PEGME) nanoparticles were evaluated by using quinine sulfate in 0.5 M sulfuric acid. The transmisson electron microscope (TEM) image and electron diffraction pattern of the ZnO-(PEGME) particles prepared by using the PEGME350 as the grafting polymers were also shown. The properties of the ZnO(PEGME) nanoparticles shwo great advantages over those of the ZnO(Ac) nanoparticles prepared through the conventional ZnAc2 route.
