Description
Seunghyun Oh and a large Korean team build in 2026 a single light sensor that sees visible light or short-wave infrared on demand. It needs none of the stacked filter layers that usually separate the two. Such dual-mode detectors serve imaging and diagnostics, yet interlayers add noise and manufacturing complexity. Their device merges an organic layer with lead sulfide quantum dots in one monolithic stack.
Controlled phase separation inside the organic layer, running both vertically and sideways, steers charge flow so cleanly that no auxiliary interlayer is needed. The result is high detectivity with little crosstalk between bands. Single-pixel imaging reconstructed sharp pictures in both bands even with the light dimmed. The dual view also let the team align silicon parts by registering front and back features. The design strategy transfers to other photoactive pairings.
