By using the gas‐evaporation technique with an induction heating method, Zn nanoparticles coated with ZnO were prepared in Ar. The Raman spectra of the Zn/ZnO nanoparticles were studied over a wide range from room temperature through liquid nitrogen temperature and up to 873 K. With heating in air, the transformations from the surface phonon mode to bulk vibrational mode in Zn/ZnO were successfully observed for the first time. © 1998 John Wiley & Sons, Ltd.
