This article reports the preparation of VO ink via a novel chemical route. The prepared VO ink has been spin coated for the synthesis of VO thin films on glass substrates. The synthesized VO thin films were annealed at 300-400 °C in air and characterized by different techniques. The X-ray diffraction data reveal the phase pure VO compound with polycrystalline nature. The scanning electron microscopy micrographs unravel that the VO thin films are smooth with few nanoflakes presented on the surfaces. An optical study reveals that transmittance and bandgap of the VO thin films decrease with annealing temperature. The bandgap of the films varies in the range of 2.8-2.9 eV. These findings have opened a new avenue for the preparation of metal oxide ink. The prepared VO ink is promising for the manufacture of low-cost VO-based photoelectrochemical cells.
本文报道了通过一种新型化学路线制备VO油墨的方法。所制备的VO油墨已通过旋涂法在玻璃基板上合成VO薄膜。合成的VO薄膜在空气中于300 - 400°C退火，并采用不同技术进行表征。X射线衍射数据表明该化合物为具有多晶性质的纯VO相。扫描电子显微镜照片显示VO薄膜表面光滑，有少量纳米薄片。光学研究表明，VO薄膜的透过率和带隙随退火温度降低。薄膜的带隙在2.8 - 2.9 eV范围内变化。这些发现为金属氧化物油墨的制备开辟了一条新途径。所制备的VO油墨有望用于制造低成本的基于VO的光电化学电池。
