Unveiling a growth temperature-dependent ultra-sensitive tetragonal scheelite BiVO₄ thin film-based gas sensor for ammonia volatilization at room temperature.

ABSTRACT: Ammonia (NH₃) vapour is considered as a hazardous volatile, which has the potential to cause health concerns in humans. Exposure to NH₃ can lead to potentially fatal, severe burn injuries to human eyes, can cause encephalopathy, and also affects various physiological systems, including the liver, the kidneys and the immune system. Due to these prime factors, the advancement of chemi-resistive ammonia gas sensors at room temperature has drawn considerable attention among researchers. In this current work, tetragonal scheelite (T_s)-BiVO₄ thin films were deposited by varying the substrate (growth) temperature via the chemical spray pyrolysis method. The deposited thin films were subjected to structural, optical, morphological and gas sensing
