Boosting the Humidity Performances of Na_0.5Bi_xTiO₃ by Tuning Bi Content.

ABSTRACT: In the field of humidity sensors, a major challenge is how to improve the sensing performance of existing materials. Based on our previous work on Na_0.5Bi_0.5TiO₃, a facile strategy of tuning the Bi content in the material was proposed to improve its sensing performance. Na_0.5Bi_xTiO₃ (x = 0.3, 0.35, 0.4, 0.45) nanocomposites were synthesized by a hydrothermal method. Humidity sensing properties of these nanocomposites were investigated in the relative humidity range of 11% to 95%. Our results show that, compared to the sensor based on nominally pure sample (Na_0.5Bi_0.5TiO₃), the sensor based on Na_0.5Bi_0.35TiO₃ exhibits boosted sensing performance of excellent li
