摘要:
Barium titanate (BT) nano-particles with different diameters were prepared by Sol-Gel method. The particle diameter was determined by XRD, and the lattice constants of nano-particles were also determined by XRD. We also measured the lattice vibration for BT nano-particles by raman scattering to discuss on the size effect. As a result, we successfully calculated the intrinsic dielectric constants for BT nano-particles by analyzing the lattice vibration. Moreover, we confirmed the shift of curie temperature by the size effect. © 2004 Hosokawa Powder Technology Foundation. All rights reserved.
