VOC decoding in vapor. a In situ solid-state luminescent sensor set-up. b Emission spectra of Eu0.47Tb0.53-CTP-COOH PVA film exposed to different VOCs for 5 min. The inset shows the photographs of color changes for the sensor incorporated with different VOCs. c Two-dimensional decoded map of VOCs based on the emission intensity ratio (I616/I592) of Eu3+ ion as x-axis and the ratio (I547/I491) of Tb3+ as y-axis
