| 英文摘要 | Ferroelectric perovskite oxides [knbo3](1-x),[baco1/2nb1/2o3-delta](x)(kbcno, delta> 0 means the existence of oxygen vacancies) solid solutions (0.1 <= x <= 0.5)were successfully synthesized by doping co and ba into the lattice of knbo3 though solid-state reaction. the band gap energy of kbcno shifts down to 2.4 ev and became visible-light-active due to the doping affection on the energy band structure comparing with that of wide-band-gap semiconductor knbo3 (3.4 ev). the x-ray diffraction and raman spectra revealed that the kbcno solid solutions are in perovsite phase and gradually transiting from orthorhombic to cubic structure with the different baco1/2nb1/2o3-delta(bcno) contents. the reduction of band gap value makes kbcno ferroelectric a promising candidate for photovoltaic materials.
