Within the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Vitality donors, are photoexcited to an psyched state, they're able to transfer their energy non-radiatively to Bi2O2Se by way of dipole–dipole interactions. This causes electrons inside the valence band of Bi2O2Se to transition into the conduction band. Within https://waiijing43197.blog-kids.com/28441722/top-guidelines-of-waiijing
