“…A roomtemperature LPG sensor based on zinc oxide/polypyrrole/lead sulde quantum dots nanocomposite lm was fabricated by Zhang et al 56 The value of maximum sensitivity they reported was 0.45 at 1000 ppm of LPG. A room-temperature LPG sensor based on a-Fe 2 O 3 /carbon nanotube nanocomposite lms was reported by Chaitongrat et al 57 Their sensor demonstrates a sensitivity of 0.05 for 7000 ppm of LPG. Saxena et al 58 demonstrated a room-temperature LPG sensor by employing CdS : SiO 2 nanocomposite thin lms.…”
