Abstract

The distribution of substituents in lead zirconate (PZ) modified by K+ (PKZ) has been studied by high-resolution Z-contrast imaging. Pronounced intensity variations were observed between various Pb columns, giving direct evidence that a number of columns had higher concentrations of (K+) substituents. High-resolution Z-contrast imaging was also performed in La+3-modified lead zirconate titanate (PLZT) for comparison.
