WO<sub>3</sub>-Based Thin Films Grown by Pulsed Laser Deposition as Gas Sensors for NO<sub>2</sub> Detection

WO<sub>3</sub>-Based Thin Films Grown by Pulsed Laser Deposition as Gas Sensors for NO<sub>2</sub> Detection

Thin films based on tungsten oxide (WO<sub>3</sub>) were grown by nanosecond pulsed laser deposition on alumina printed-circuit boards to fabricate electrochemical sensors for nitrogen dioxide (NO<sub>2</sub>) detection. Samples exposed to thermal annealing (400 °C for 3 h) w...
