From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Power donors, are photoexcited to an excited point out, they are able to transfer their Power non-radiatively to Bi2O2Se through dipole–dipole interactions. This results in electrons from the valence band of Bi2O2Se to transition on the conduction band. https://waiijing87531.theobloggers.com/34392873/ไวจร-ง-no-further-a-mystery
