LITTLE KNOWN FACTS ABOUT WAIIJING.

Inside the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as energy donors, are photoexcited to an fired up state, they can transfer their energy non-radiatively to Bi2O2Se as a result of dipole–dipole interactions. This will cause electrons while in the valence band of Bi2O2Se to transition on the conduction band. While in t
