Abstract
Centimeter-sized CsPbBr<sub>3−3n</sub>X<sub>3n</sub> single crystals were grown using the modified Bridgman method. Eight filter-free narrowband photodetectors were fabricated based on the CsPbBr<sub>3−3n</sub>X<sub>3n</sub> crystals utilizing the concept of charge collection narrowing. A filter-free color image sensor was constructed using these eight CsPbBr<sub>3−3n</sub>X<sub>3n</sub> narrowband photodetectors.
