While in the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as energy donors, are photoexcited to an energized state, they can transfer their Electricity non-radiatively to Bi2O2Se by means of dipole–dipole interactions. This causes electrons during the valence band of Bi2O2Se to transition into the conduction band. During https://waiijing54107.dbblog.net/1496294/an-unbiased-view-of-waiijing
