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.
