5 SIMPLE TECHNIQUES FOR WAIIJING

From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Power donors, are photoexcited to an excited point out, they could transfer their Vitality non-radiatively to Bi2O2Se via dipole–dipole interactions. This causes electrons from the valence band of Bi2O2Se to transition towards the conduction band. During the PbS QDs/B
