Fig. 4: Sensing properties of BPCBT microwires to HCl vapor.
From: Stable organic self-assembled microwire lasers for chemical vapor sensing
a Photoluminescence and b lasing spectra of BPCBT microwires before and after exposure to HCl vapor. Insets are optical microscopy images of microwires. Scale bars are 5 μm. c Quenching efficiency of lasing from a BPCBT microwire upon exposure to HCl vapor with different concentrations. Error bars represent the deviation of three measurements. d Cycles of lasing quenching and recovery from a BPCBT microwire upon exposure to HCl vapor and air with 10 min intervals at constant pump energy.
