From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as energy donors, are photoexcited to an psyched condition, they are able to transfer their Electrical power non-radiatively to Bi2O2Se by way of dipole–dipole interactions. This leads to electrons during the valence band of Bi2O2Se to changeover for the https://www.facebook.com/wiijing.net
