A high-sensitivity gas sensor based on SCLT is demonstrated in this paper. The oxidizing and reducing gases which act as electron dedoping (e-dedoping) and doping (edoping) agents on the transistor active layer is investigated. Dedoping and doping the active layer varies the potential distribution in the vertical channel, and changes the output current density. The lowest detectable concentration...
A near-infrared proximity sensor array is achieved by integrating a polymer light-emitting diode and a polymer photodetector (PD). A green emission is converted into deep red peaked at 670 nm by the inorganic phosphor Intematix R670 with quantum efficiency of over 20%. A bandpass filter is used to select a spectral tail of phosphor luminescence with a wavelength above 700 nm. The emissive polymer...
