TiO2nanowire array based interferometric sensor

  • 摘要:开发一种新型TiO2纳米线阵列干涉传感器。首先,通过水热合成法在FTO导电玻璃表面制备了TiO2纳米线阵列薄膜。然后,以此复合结构作为传感芯片,利用Kretschmann 棱镜耦合结构,构建了基于Kretschmann结构的波长调制型薄膜干涉传感器。最后,以氯化钠水溶液为待测液体介质研究了该传感器对环境介质折射率的灵敏性能。结果表明:该传感器对1.333 5~1.360 4范围内的折射率有很好的响应。TM模式下,在0~3%与3~15%浓度范围内,氯化钠浓度与该传感器的反射光强度分别呈现了良好的线性关系。TE模式下,在0~3%浓度范围内,氯化钠浓度与吸收强度存在良好的线性关系,而波长基本不变;而在3~15%浓度范围内,随着氯化钠浓度的增加,波长逐渐红移,氯化钠浓度与波长也具有良好的线性关系。
