Freestanding crystalline PbZrO3 nanoparticles with an average size of 15 nm were synthesized by the modified sol–gel method and characterized by X-ray diffraction and electron microscopy. Dielectric studies indicated that the paraelectric to antiferroelectric phase
transition in the PbZrO3 nanoparticles was observed around at 205 C which was at 233 C for PbZrO3 bulk material. A single leaky ferroelectric loop was observed instead of an antiferroelectric double hysteresis loop which may be because of the defects such as grain boundaries
and the pores in the sample because the sample was not sintered at higher temperatures to retain the nanoscale dimension of the PbZrO3 particles.
ADVANCED SCIENCE LETTERS is an international peer-reviewed journal with a very wide-ranging coverage, consolidates research activities in all areas of (1) Physical Sciences, (2) Biological Sciences, (3) Mathematical Sciences, (4) Engineering, (5) Computer and Information Sciences, and (6) Geosciences to publish original short communications, full research papers and timely brief (mini) reviews with authors photo and biography encompassing the basic and applied research and current developments in educational aspects of these scientific areas.
