The highly selective detection of trace gases using transparent sensors at room temperature remains challenging. Herein, transparent nanopatterned chemiresistors composed of aligned 1D Au–SnO2 nanofibers, which can detect toxic NO2 gas at room temperature under visible light illumination is reported. Ten straight Au–SnO2 nanofibers are patterned on a glass substrate with transparent electrodes assisted...
In article number 2100438, Jong‐Heun Lee and co‐workers report transparent gas sensors composed of aligned one‐dimensional Au–SnO2 nanofibers with extremely low coverage, transparent electrode, and glass substrate, which can detect harmful NO2 at room temperature under visible light illumination or natural sunlight. The transparent sensor design enables the unnoticeable installation of gas sensors...
A Highly ordered CdS nanoflake array was fabricated by CVD, and its gas sensing characteristics were investigated. The sensor exhibited high response (resistance ratio) of 89% to 5 part per million (ppm) nitrogen dioxide (NO2) under green LED illumination (wavelength 500–540nm, irradiance 21W/m2) with excellent selectivity and little interference by humidity. Moreover, the sensor showed promising...
