Abstract
|
|
|
|
X-ray diffraction analysis and infrared spectrophotometry were used to investigate the crystal structures and the bonding characteristics in (Pb1-xNdx)(Zr1-yTiy)O3 (PNZT), which has a perovskite structure. As Pb2+ of PZT was substituted by 8∼12 atom% Nd3+ ion, the structures were changed to cubic from tetragonal and its transmission had maximum value. Transmission increased as the stretching force constant (ks) of unit cell increased. It is supposed that the electro-optic characteristics might occur due to electron-transition from HOMO to LUMO of titanium ion.
