In situ XPS spectra of Ti 2p (a) and O 1s (b) in TiO2 in the dark and under illumination; (c) TOF-SIMS spectra of D depth profile of TiO2 in the dark and under illumination, in the mixture solution of ...
As the acronym suggests XPS (X-ray photoelectron spectroscopy) is a spectroscopic technique. An XPS spectrum is displayed as the number of photoelectrons collected by the detector as a function of ...
