Inside the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Electricity donors, are photoexcited to an psyched condition, they are able to transfer their energy non-radiatively to Bi2O2Se as a result of dipole–dipole interactions. This brings about electrons in the valence band of Bi2O2Se to changeover for the https://www.youtube.com/@%E0%B9%84%E0%B8%A7%E0%B8%88%E0%B8%A3%E0%B8%B4%E0%B8%87
