Red shifts for the three peaks and their corresponding linear correlations. (a) Red shifts for the three peaks of C-PSRFs when exposed to ethanol vapor with different concentrations. (b) The linear correlations between the red shifts of the three peaks and the peaks' initial positions when exposed to a certain concentration of ethanol vapor. The inset is the linear correlation between the slope coefficient and the concentration of ethanol.
