Key Points

This research aims to explore how annealing temperature alters the structure and optical properties of SnS thin films and their subsequent effect on CO2 gas sensing performance.
Thin films of SnS were deposited by thermal evaporation with a thickness of 400 nm.
The influence of varying annealing temperatures on film characteristics was examined.
Gas sensing performance in relation to structural and optical modifications of the films was assessed.
Higher annealing temperatures improved gas sensing performance, demonstrating enhanced sensitivity to CO2.
Distinct structural and optical changes were correlated with temperature variations, leading to optimized film properties.
