The electronic structure variations induced by the transition have been observed through X-ray photoelectron spectra. The local screening effects are more important than the bulk in structural unstable NiO nanoparticles, which is in contrast to the case of the CuO nanoparticles. 关键词: NANOSTRUCTURES; OPTICAL PROPERTIES; PHASE TRANSITIONS; PHOTOELECTRON SPECTROSCOPIES SPECTROSCOPIES; TRANSITION-METAL COMPOUNDS; CLUSTER-MODEL; PHOTOEMISSION
