Inside the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Strength donors, are photoexcited to an psyched point out, they could transfer their Strength non-radiatively to Bi2O2Se by way of dipole–dipole interactions. This will cause electrons from the valence band of Bi2O2Se to transition on the conduction band. https://waiijing08642.arwebo.com/51419701/rumored-buzz-on-waiijing
