Facile fabrication of NaTaO3 film and its photoelectric properties
چکیده انگلیسی

Uniform NaTaO3 thin film was prepared on tantalum foils by a facile low temperature hydrothermal method. X-ray diffraction and field emission scanning electron microscopic characterizations revealed the film was well synthesized. The influence of synthesis temperature and time on the crystal structure and morphology of the film was investigated. Then Au film was deposited on NaTaO3 to fabricate interdigitated electrodes and photoelectric effects of the detector were systematically studied. At 5 V bias, the photocurrent was 0.56 μA under the irradiation of 260 nm ultraviolet light, which was 7 times larger than that under dark condition. The spectral responsivity of the device shows good sensitivity to ultraviolet light from 250 to 350 nm and the response peak appeared at 260 nm. These experimental results demonstrate the promising application of NaTaO3 in ultraviolet detection.
