During the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Electricity donors, are photoexcited to an enthusiastic state, they will transfer their Power non-radiatively to Bi2O2Se as a result of dipole–dipole interactions. This will cause electrons inside the valence band of Bi2O2Se to changeover for the conduction band. https://waiijing32086.designertoblog.com/59797431/waiijing-things-to-know-before-you-buy
