During the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Electricity donors, are photoexcited to an psyched point out, they will transfer their Strength non-radiatively to Bi2O2Se by way of dipole–dipole interactions. This brings about electrons from the valence band of Bi2O2Se to changeover into the conduction band. https://waiijing32086.worldblogged.com/34086054/waiijing-no-further-a-mystery
