From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Power donors, are photoexcited to an psyched point out, they will transfer their Strength non-radiatively to Bi2O2Se by way of dipole–dipole interactions. This triggers electrons inside the valence band of Bi2O2Se to transition to the conduction band. During https://www.youtube.com/@%E0%B9%84%E0%B8%A7%E0%B8%88%E0%B8%A3%E0%B8%B4%E0%B8%87
