From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Electricity donors, are photoexcited to an psyched point out, they can transfer their Electricity non-radiatively to Bi2O2Se through dipole–dipole interactions. This results in electrons during the valence band of Bi2O2Se to changeover on the conduction band. While in https://www.facebook.com/wiijing.net
