Researchers at Nagoya University report in ACS Nano a gallium-doped zinc oxide
(GZO) nanosheet optical sensor that can let a single pixel detect red, green and
blue light simultaneously, potentially replacing the decades-old Bayer color
filter array. If commercialized, the technology could enable smaller sensors and
thinner smartphone camera modules, higher‑resolution medical imaging devices,
more compact automotive and aerospace sensors, and simpler manufacturing
processes.
