From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as energy donors, are photoexcited to an excited condition, they can transfer their energy non-radiatively to Bi2O2Se by dipole–dipole interactions. This causes electrons while in the valence band of Bi2O2Se to changeover towards the conduction band. From the PbS https://waiijing08652.livebloggs.com/34506814/top-latest-five-waiijing-urban-news
