Inside the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Power donors, are photoexcited to an thrilled state, they are able to transfer their Vitality non-radiatively to Bi2O2Se via dipole–dipole interactions. This brings about electrons while in the valence band of Bi2O2Se to transition for the conduction band. https://waiijing76420.dm-blog.com/28333432/the-ultimate-guide-to-waiijing
