5 SIMPLE TECHNIQUES FOR WAIIJING

Within the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Vitality donors, are photoexcited to an enthusiastic state, they could transfer their Vitality non-radiatively to Bi2O2Se as a result of dipole–dipole interactions. This triggers electrons in the valence band of Bi2O2Se to transition to the conduction band. While in
