Inside the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Power donors, are photoexcited to an energized point out, they are able to transfer their Vitality non-radiatively to Bi2O2Se via dipole–dipole interactions. This will cause electrons inside the valence band of Bi2O2Se to transition on the conduction band. https://waiijing98652.canariblogs.com/the-definitive-guide-to-waiijing-43624763
