During the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Vitality donors, are photoexcited to an fired up state, they will transfer their Strength non-radiatively to Bi2O2Se by dipole–dipole interactions. This brings about electrons from the valence band of Bi2O2Se to changeover to the conduction band. Inside the https://waiijing76420.bloggactivo.com/27934442/waiijing-an-overview
