Crystallographic characterization and NO2 gas sensing property of LnFeO3 prepared by thermal decomposition of LnFe hexacyanocomplexes, Ln[Fe(CN)6]·nH2O, Ln = La, Nd, Sm, Gd, and Dy
Abstract
Finer perovskite-type LnFeO3 (Ln=La, Nd, Sm, Gd, and Dy) powders were prepared by the thermal decomposition of heteronuclear complexes, Ln[Fe(CN)6]·nH2O. The prepared LnFeO3 showed a p-type semiconductive behavior and the highest enhancement of conductance due to NO2 exposure was observed for SmFeO3 sensor. The atomic ratio of adsorbed oxygen Oad increased with the surface coverage of Ln, expressed as Ln/(Ln+Fe). Experimentally, the atomic ratio...
