Quantum dots (QDs), celebrated for their tunable bandgaps and confined excitons, are a focal point in optoelectronics1. Their unique properties have catalyzed progress in a diverse array of applications, including solar cells, light-emitting diodes (LEDs), detectors, and optical imaging2-4.Particularly, perovskite and chalcogenide QD heterostructures present a compelling platform for integrating visible and near-infrared spectral responses through effective carrier transfer. However, a lack of controllable and low-cost synthesis methodologies currently curtails the development and application of such intricate structures. Herein, we report a facile and replicable in-situ room-temperature synthesis approach for yielding spectrally tunable, low-cost processing all-CQD CsPbBr3-PbS heterostructures.
