Commercially available SnO 2 powder is used in the form of pellets. Copper is deposited on SnO 2 pellets by ablation with Excimer laser using copper target to increase their sensitivity for CO and LPG. The samples were ablated for a variable time of 1, 1.5, 2, and 2.5 min and sintered at 500°C, 550°C, 600°C, and 650°C for 5 h, respectively. The samples that were ablated for 1.5 min and sintered at 550°C show the highest sensitivity for CO and LPG at 180°C and 280°C, respectively. The structural characterization was carried out using X‐ray diffraction, scanning electron micrography, and energy‐dispersive X‐ray spectroscopy.
