中文摘要:
      利用溶胶–凝胶旋涂法和后退火工艺在FTO导电玻璃上制备了钨镍共掺杂V2O5薄膜,研究了薄膜在不同温度和不同偏压下的光电特性和相变特性。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM) 和X射线光电子能谱仪(XPS) 测试了钨镍共掺杂V2O5薄膜的晶体结构、表面形貌和组分,分析了不同钨镍共掺杂浓度对V2O5薄膜相变光电特性的影响。结果表明,当钨和镍的掺杂质量分数分别为3 %和1.5 %时,钨镍共掺杂的V2O5薄膜的相变温度为218.5 ℃,在可见光范围内有较高的透过率,在近红外1310 nm波长处的光学透过率达48.83%,与未掺杂V2O5薄膜的光学透过率相比提高了10.29%,薄膜电阻降低了30.53%,热致回线宽度收窄为15 ℃,说明钨镍共掺杂的V2O5薄膜具有良好的可逆相变光电特性,有望在新型光电器件领域得到较好的应用。
英文摘要:
      In this paper, tungsten-nickel co-doped V2O5 films were prepared on FTO conductive glass by using sol-gel spin coating and annealing to study their photoelectric and phase transition properties at different temperatures and different bias voltage. The crystal structure, surface morphology and components of tungsten-nickel co-doping V2O5 films were tested by XRD, SEM and XPS to analyze the effects of different tungsten-nickel co-doping concentrations on the phase transition photoelectric properties of V2O5 films. The results show that when the doping concentrations of tungsten and nickel were respectively 3% and 1.5%, tungsten-nickel co-doped V2O5 films had a phase transition temperature of 218.5 ℃, a higher transmittance in the visible light range and the transmittance of 48.83% at 1310 nm wavelength. Comparing with the undoped V2O5 films, the optical transmittance and sheet resistance of the co-doped V2O5 films increased 10.29% and decreased 30.53%, respectively, and the thermal hysteresis loop width was also narrowed to 15 ℃. It is expected to have better applications in the field of new optoelectronic devices based on their excellent reversible phase transition photoelectric properties.
