BaTiO3 has Hub Cap Covers and Accessories been investigated nearly several decades due to its excellent ferroelectric and dielectric properties.However, the property evolution of BaTiO3 with a particle size of sub-10 nm is still unclear because of the difficulty during the fabrication and characterization.Here, a series of BaTiO3 nanoparticles with the average particle sizes of 2.8, 4.

5 and 8.1 nm are achieved, and their phase structure, ferroelectric and dielectric properties are skillfully characterized.With the particle size decreasing from 8.1 to 2.

8 nm, the nanoparticles show a declining non-centrosymmetry, nonlinear response, ferroelectricity and dielectric Accessories - Gloves constant.Nevertheless, the 2.8 nm BaTiO3 nanoparticles still possess observable second harmonic generation, ferroelectric polarization switching behavior and butterfly loop, showing weak but distinguishable ferroelectricity.This research depicts a detailed ferroelectric and dielectric property evolution in sub-10 nm BaTiO3 nanoparticles, which provides theoretical basis and promising candidate for the future ferroelectric applications.
