Within the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Electricity donors, are photoexcited to an fired up state, they can transfer their energy non-radiatively to Bi2O2Se by dipole–dipole interactions. This leads to electrons in the valence band of Bi2O2Se to transition on the conduction band. In the https://socialicus.com/story2872847/top-%E0%B9%84%E0%B8%A7%E0%B8%88%E0%B8%A3-%E0%B8%87-secrets
