Abstract

Raman spectra acquired from spherical SnO ₂ nanocrystals prepared by pulsed laser ablation and hydrothermal synthesis exhibit three oxygen-vacancy-related Raman modes at 234, 573, and 618 cm ^-1. The peak location and intensity vary with annealing temperature under O ₂ finally approaching those of bulk materials. Density functional calculation discloses that the three Raman modes stem from subbridging, in-plane, and bridging oxygen vacancies, respectively. Raman spectra can thus be used to discern different types of oxygen vacancies in SnO ₂ nanocrystals. Copyright © 2012 John Wiley & Sons, Ltd.
