英文摘要	In this study, we explore a new strategy to tailor the growth process of monodisperse nanocrystals. By means of X-ray diffraction, high-resolution transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray fluorescence spectrometry, and X-ray absorption spectroscopy, it is found that the growth of ceria followed Ostwald ripening, and polydispersed ceria nanocrystals were obtained in a hydrothermal condition. With the addition of cobalt to the growing ceria nanocrystals, cobalt acted as a surface dopant and preferred to bind on the surface of large-sized ceria nanocrystals via Co-O-Ce bonds. The binding could modulate the Ostwald ripening process and narrow the size distribution. With the competition between cobalt dopants and Ce monomers onto the surface of nanocrystals, monodisperse cobalt-doped nanocrystals were formed. This route is expected to be applicable to a variety of monodisperse doped nanocrystals.
