While in the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Electrical power donors, are photoexcited to an energized condition, they are able to transfer their energy non-radiatively to Bi2O2Se through dipole–dipole interactions. This results in electrons inside the valence band of Bi2O2Se to transition to your conduction https://waiijing86430.blogadvize.com/34935843/facts-about-waiijing-revealed
