Abstract

The pyroelectric infrared device (PID) with high absorptivity graphene electrodes (GE) is reported in this paper. The sensitive film of the device is prepared by using piezoelectric poly(vinylidene fluoride-trifluoroethylene) composite materials. We use black graphene conductive ink to prepare the electrodes by using screen-printing technology. The black graphene electrode has high absorptivity at the range from near-infrared to mid-infrared. In order to verify the PID-GE, the control group (CG) device, which uses the Ni/Fe electrode, is also fabricated. When the chopping frequency is 3 Hz, the peak-to-peak value (Vpp) and signal to noise ratio (SNR) of the PIR-GE are enhanced 204% and 31.65%, respectively, relative to that of the PIR-CG. The largest detectivity of the PID-GE is about 1.58×108cm·Hz1/2·W1; it is approximate to that of the commercial device LME-352-#, which is prepared by using LiTaO3 with the black layer.
