From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Vitality donors, are photoexcited to an excited point out, they might transfer their Power non-radiatively to Bi2O2Se by way of dipole–dipole interactions. This causes electrons in the valence band of Bi2O2Se to changeover to the conduction band. During the PbS QDs/Bi
