Abstract EN
Fascicular KNbO3 nanowires with tetragonal perovskite structures and ultrasmall diameters are synthesized by hydrothermal route at about 150°C for 24 hours.
The concentrations of medium alkalinity have influenced phase structures and the final morphologies of the products significantly by modifying the conditions in process.
The as-prepared KNbO3 nanowires exhibit three phase transitions at about 343, 454.7, and 623 K as the temperature increases from 250 to 700 K.
The band gap is about 3.78 eV for KNbO3 nanowires.
Photoluminescence study at room temperature reveals two visible light emission bands peaking at ~551 and 597 nm, respectively, which may be due to the oxygen vacancies, site niobium (occupy the location of Nb), and antisite niobium (occupy the location of K) in KNbO3 nanowires.
