Disruptive infrared image sensors enabled by quantum dots

Abstract: Sensors based on quantum dot photodiodes promise quality and accessibility improvement of infrared imaging. We demonstrate miniaturization by sub‐2‐μm pixel pitch arrays. Functionality is confirmed with external quantum efficiencies above 40% at 1450 nm. Monolithic integration enables high throughput and wide deployment of short‐wave infrared (SWIR) imagers in applications that previously could not afford them.

“…[1][2][3][4][5][6][7] NIR fluorescent dyes primarily include inorganic materials (such as NIR quantum dots) and organic fluorescent molecules (such as fluorescent proteins). [8][9][10][11] Traditional dyes such as coumarins and anthraquinones are mostly in the visible range of absorption and emission, with weak tissue penetration. Newer dyes such as rhodamines and single-walled nanotubes have excellent optical properties, but are either more toxic or more costly to synthesize with complex processes.…”
