During the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Vitality donors, are photoexcited to an enthusiastic state, they can transfer their Electricity non-radiatively to Bi2O2Se by means of dipole–dipole interactions. This will cause electrons inside the valence band of Bi2O2Se to changeover on the conduction band. In https://waiijing75319.qowap.com/87914458/the-ไวจร-ง-diaries
