- Abstract
Multimodal Gas Sensors In article number 2202207, Hyung Woo Lee, Han Seul Kim, Jin Woo Choi, and co‐workers study the mechanism of hydroxyl‐induced reversible phase transition of Cs3Cu2I5 and CsCu2I3 and fabricate electrical‐optical responsible multimodal gas sensors. The hydroxyl sensors show optical red‐shifted emission and electrical resistance increment in 5s and 1 min, respectively. The sensor can be repeatably operated under room temperature with a low operation voltage of 1V with high stability over 1 year.
