Sb-doping effects on optical and electrical parameters of SnO2 films

Surface‐related investigations to characterize different preparation techniques of Sb‐doped SnO2 powders

“…This is in good agreement with data of previous authors, 22,23,28,29 indicating that bulk doping with Sb leads to a change of electrical and morphological properties of SnO 2 powders. On the basis of these data the relative amount of incorporated antimony can be determined.…”

Aqueous latex/ceramic nanoparticle dispersions: colloidal stability and coating properties

“…The refractive indices of ATO [33][34][35][36][37] and ITO [38][39][40][41][42][43] in the range of visible light are a function of composition, processing condition, and wavelength. Typically, n of ATO ranges from 1.72 to 2.68 [33][34][35][36][37]; that of ITO from 1.7 to 2.2 [37][38][39][40][41][42][43]. As the processing conditions for the ATO and ITO used here are not known, compositional similarity was used as the selection criterion for the limiting refractive indices.…”

“…This difference is likely attributed to two causes. First, the ITO nanoparticles may have a lower conductivity in comparison with the ATO nanoparticles [33][34][35][36][37][38][39][40][41][42][43]. To test this hypothesis, ATO and ITO powder coatings were prepared with aqueous dispersions containing ATO or ITO alone.…”

Measurement and Properties of the Oxide Ionic Conductivity of β- and δ-Phases in the Binary (Bi2O3)1−x (Tb4O7) x System

“…Bismuth oxide and doped bismuth oxide systems exhibit a complex array depending on dopant concentration, temperature, and atmosphere. [1][2][3][4][5] Six polymorphs of Bi 2 O 3 have been reported in the literature: monoclinic α-Bi 2 O 3 , tetragonal β-Bi 2 O 3 , cubic (bcc) γ -Bi 2 O 3 , cubic (fcc) δ-Bi 2 O 3 , orthorhombic ε-Bi 2 O 3 , and triclinic…”

[1][2][3][4][5] Six polymorphs of Bi 2 O 3 have been reported in the literature: monoclinic α-Bi 2 O 3 , tetragonal β-Bi 2 O 3 , cubic (bcc) γ -Bi 2 O 3 , cubic (fcc) δ-Bi 2 O 3 , orthorhombic ε-Bi 2 O 3 , and triclinic ω-Bi 2 O 3 phases. The phase transition from the monoclinic α-phase, to the high-temperature cubic δ-phase occurred at approximately 730 • C. The δ-phase was also found to be stable up to its melting point of approximately 825 • C. On cooling, the δ-phase from high temperature to room temperature, a large hysteresis was observed, with the possible occurrence of two intermediate metastable phases: the tetragonal β-phase or the bcc g-phase.…”
