| Abstract: | Tin oxide nanotentacles were synthesized by combustion chemical vapor deposition in air. Their surface composition and optical properties were then investigated using X‐ray photoelectron spectroscopy (XPS) and Raman spectroscopy. XPS core level spectra indicate that these nanotentacles are of high oxygen vacancy with chemical composition of about SnO1.6, which is also supported by the Sn Auger parameter. Besides SnO2, the optical properties of SnO were detected in Raman spectrum. Moreover, two new Raman peaks were found for the SnO2 phase because of the high oxygen vacancy concentration.
