摘要:

A kind of lead-free ferroelectric nanorods, (K0.5Bi0.5)(0.4)Ba0.6TiO3, has been prepared by the sol-gel process. The phase formation, structure and morphological analyses of (K0.5Bi0.5)(0.4)Ba0.6TiO3 were investigated by XRD, FTIR, Raman and TEM. The results revealed that single-crystalline (K0.5Bi0.5)(0.4)Ba0.6TiO3 nanorods with width around 80 to 120 nm, and length around 200-300 nm were obtained by calcining dried gels at 800 degrees C for 2 h. Raman analysis of (K0.5Bi0.5)(0.4)Ba0.6TiO3 nanorods indicated that A(1) (TO2) and E(TO) mode incorporated into one broad peak at around 285 cm(-1), which can be attributed to the cation disorder (Bi, K, Ba) on the 12-fold coordinated A site of ABO(3) structure.
