  • Publication number: 20240076543
    Abstract: The present disclosure provides a weakly-confined semiconductor nanocrystal, a preparation method therefor and use thereof. A size of the nanocrystals is larger than an exciton diameter thereof; excitons in the nanocrystal are dynamic excitons, electron-hole Coulomb interaction of the dynamic excitons is insufficient to bind electrons and holes into stable bound excitons at operating temperatures, and the electrons and the holes of the dynamic excitons are constrained by boundaries of the nanocrystal. Since the excitons in the weakly-confined nanocrystals herein possess the characteristics of dynamic excitons, the nanocrystals herein possess unique optical and photoelectric properties distinct from conventional semiconductor nanomaterials. It holds unique value for applications requiring broad-spectrum emission (such as lighting) and significant importance for photovoltaic solar devices, photoelectric detectors, and photocatalysis.
