During the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Power donors, are photoexcited to an excited condition, they're able to transfer their Power non-radiatively to Bi2O2Se by means of dipole–dipole interactions. This brings about electrons from the valence band of Bi2O2Se to changeover to the conduction band. https://dominickwchow.qodsblog.com/28312402/the-ไวจร-ง-diaries
