Visible-Blind Infrared Upconversion Devices for Image Sensing

Abstract

Epitaxial semiconductors dominate infrared sensing applications to date, albeit their intrinsic opacity and brittleness per se limit the possibilities of developing novel technologies. Here, we demonstrate a visible-blind, all-organic infrared visualization device that can differentiate the incident infrared power density down to 12 μW cm-2 from the intense ambient light illumination of 2000 lux with the help of a hybrid organic inorganic metal halide perovskites as a bandpass filter.
