“…If for rough estimate of the optical absorption energy we increase the calculated value by the same correction ϭ2.21 eV used to correct the band-gap width, we obtain about 3.4 eV. It is interesting to note that this value is very close to the maximum of the broad band at about 3.4 eV attributed to F centers ͑neutral vacancies in yttria-stabilized zirconia 34 and V 0 . The calculated reaction energies can be affected by several factors.…”

“…There have been suggestions that negatively charged vacancies (FЈ centers 34 ͒ can also exist in zirconia. Therefore we considered trapping of an additional electron at the neutral oxygen vacancy V 4 0 and creation of the negatively charged vacancy V 4 Ϫ .…”

“…Recent reports suggest that the surface chemistry of YSZ can change under conditions commonly encountered in operating SOFCs. 15,24,[41][42][43] Ex situ studies found that heating a YSZ sample to 800 C in a reducing atmosphere and then cooling the sample back down to room temperature resulted in a surface reduced phase of YSZ that was stable at ambient temperatures and atmospheres. 15 Data discussed below show how spatially resolved, relative oxide ion surface concentrations can be inferred using in situ vibrational Raman scattering.…”

“…The typical result of this material . Thus optical spectroscopy [3][4][5][6], procedure is a tongue-shaped blackened region in the EPR measurements [6][7][8][9][10][11][12][13][14][15][16][17][18], conductivity measurecenter of the specimen since the surfaces of the ments [1,6,19,20], electron microscopy [21], X-ray specimen can still act as oxygen sources. Essentially, studies [7], dielectric measurements [22] and meathe activity of oxygen in the reduced material is surements of elastic properties [23,24] were percontrolled kinetically rather than thermodynamically.…”
