Abstract

This talk will present the designs of polymeric upconversion imagers that combine photo-sensing and display in a compact structure, to enable infrared visualization to 1300 nm. The organic photodetectors are further improved by incorporating a new heterojunction interlayer to trigger trap-assisted photomultiplication. The interlayer served to suppress the dark current and enhance the photoresponse. The large active area of 2 square cm enabled demonstrations such as object inspection, imaging through smog, and concurrent recording of blood vessel location and blood flow pulses.
