Fig. 5: Enhanced sensing properties of BPCBT microwires to chemical vapors.
From: Stable organic self-assembled microwire lasers for chemical vapor sensing
a Mechanism of lasing sensor based on the competition between nonradiative transition of charge transfer (CT) to HCl and radiative ICT transition of BPCBT. b Quenching efficiencies of photoluminescence and lasing from BPCBT microwires upon exposure to chemical vapors of HCl, HBr, HI, HNO3, acetone, ethanol, and water, respectively. Error bars represent the deviation of three measurements.
