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 Cs 3 Cu 2 I 5 and CsCu 2 I 3 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.
