WAIIJING THINGS TO KNOW BEFORE YOU BUY

From the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Power donors, are photoexcited to an thrilled point out, they will transfer their Vitality non-radiatively to Bi2O2Se via dipole–dipole interactions. This causes electrons in the valence band of Bi2O2Se to changeover into the conduction band. Inside the PbS QDs/Bi2O2S
