In the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Vitality donors, are photoexcited to an thrilled state, they can transfer their Vitality non-radiatively to Bi2O2Se by dipole–dipole interactions. This triggers electrons in the valence band of Bi2O2Se to changeover for the conduction band. While in the PbS https://waiijing97541.blog4youth.com/28862863/the-greatest-guide-to-ไวจร-ง
