“…Referring to Table , both experiments (PL, PES, XPS, UPS, RPS, XAS) and calculations (DFT, e.g. LDA, GGA+U, B3LYP, sX, HSE06) agree at least that the defects in TiO 2 , which are located around 1 eV below the CB, are Ti 3+ -type ,,,, and show d–d transitions/3d-character and an EPR signal of paramagnetic Ti 3+ . , Measured peaks suffer from ∼0.5 eV fwhm, with the maximum mostly between 0.5 and 1.7 eV, ,,,,,,− so the defects in TiO 2 can be caused either by oxygen vacancies (V O ) or Ti interstitials (Ti int ), and titania layers could correspondingly be a reduced form of TiO 2 , i.e., an O-poor TiO 2– x or a Ti-poor Ti 1– x O 2 . Since consecutively distinguishing between those two defect types experimentally by localizing them in the band gap, the debate on the nature of defects in TiO 2 , found in the references of this paragraph, still goes on.…”

“…Titania (TiO 2 ) has been applied within research areas such as photocatalysis [ 93 ], sensing [ 94 ] and separation science [ 95 ]. TiO 2 exists in three mineralogical crystal phases: anatase, rutile and brookite.…”

“…Os campos de aplicação deste material incluem a construção de nariz eletrô-nico, dispositivos opto-eletrônicos, células solares, "displays" de cristal líquido, catalisadores e sensores de gases [37][38][39][40][41][42][43][44][45][46] . Esta última é uma das principais aplicações do dióxido de estanho.…”
