A study of microstructural and optical properties of nanocrystalline ceria thin films prepared by pulsed laser deposition

Operando Tracking of Electrochemical Activity in Solid Oxide Electrochemical Cells by using Near‐Infrared Imaging

“…Exposing ceria to reducing conditions has been reported to result in small changes in the bandgap of ceria [at higher energies (>3.5 eV) than those directly pertinent to our emission wavelengths, >720 nm, <1.72 eV]. The most pertinent change is an increased index of refraction, ∼2.2 to 2.7, which is consistent with the reduced emission intensity observed under reducing conditions for ceria . The higher index of refraction results in a higher reflectivity and lower emissivity.…”

[34,35] The higher index of refraction resultsi nahigher reflectivity and lower emissivity.T he lower emissivity reduces the NIR intensity we observe as long as the intensitiesh ave ag reater contributionf rom SOC emission rathert han reflection from the surroundings. Strong evidence that the cell emission rather than reflection dominates in our studies is found by recognizing that lower intensities are observed for the regions with bare Au and ceria with Au underneath.…”

Thermal stability of CeO2/ZrO2 multilayer thin films prepared by pulsed laser deposition

“…The CeO 2 and ZrO 2 layers were deposited alternately to obtain a total of 25 bi-layers at an optimized oxygen partial pressure of 3u10 -2 mbar at room temperature [10]. The CeO 2 layer thickness was 10 nm, while the ZrO 2 layer thickness was varied as 10, 20 and 30 nm.…”

Sol–gel derived ZnO–CeO2 thin films on glass substrate

“…There are many reports dealing with the deposition of CeO 2 thin films, and CeO 2 layers with excellent preferred orientation can be grown by reactive DC magnetron sputtering, pulsed laser deposition, electron beam evaporation, spray pyrolysis, and sol-gel methods [18][19][20][21][22][23][24]. The sol-gel method has some advantages such as high degree of homogeneity of the films, which can also be achieved in multicomponent systems, and also allows large-area coatings to be prepared at low cost over others [25].…”
