Charge distribution changes in Bi- and Pb-3d transition metal perovskite type oxides were examined by comprehensive precise structural analysis, spectroscopy, and theoretical investigations. The change in the depth of the d level of the transition metal caused the intermetallic charge transfer. A temperature-induced charge-transfer transition in chemically modified BiNiO results in technologically important negative thermal expansion.
通过全面精确的结构分析、光谱学和理论研究，研究了铋和铅3d过渡金属钙钛矿型氧化物中的电荷分布变化。过渡金属d能级深度的变化导致了金属间电荷转移。化学改性的BiNiO中温度诱导的电荷转移跃迁导致了具有重要技术意义的负热膨胀。
