THE ULTIMATE GUIDE TO WAIIJING

Inside the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Electricity donors, are photoexcited to an enthusiastic condition, they will transfer their Vitality non-radiatively to Bi2O2Se as a result of dipole–dipole interactions. This causes electrons in the valence band of Bi2O2Se to transition on the conduction band.
