Visible LEDs Enable Sensor Response Activation at Room Temperature
MOSCOW, Nov. 13, 2017 — Scientists have discovered a mechanism that allows hydrogen sensors to work under visible light, without heating, therefore enabling the sensor to work at room temperature. The discovery, based on nanocrystalline metal oxides, could reduce the energy consumption of the sensor and expand its scope. Until now, most research has been devoted to the influence of UV illumination on the sensor properties of nanocrystalline metal oxide to oxidizing gases. However UV LEDs have lower efficiency
