Summary

High hydrostatic pressure increases the band gap of cadmium selenide/cadmium zinc sulfide (CdSe/CdZnS) core-shell nanoplatelets. This occurs slower than in bulk materials due to core hardening from strain.

Area of Science:

  • Materials Science
  • Nanotechnology
  • Solid State Physics

Background:

  • Optical properties of nanomaterials under pressure reveal mechanical behavior.
  • Reduced dimensionality significantly influences material properties.

Purpose of the Study:

  • Investigate the effect of high hydrostatic pressure on the optical band gap of CdSe/CdZnS core-shell nanoplatelets.
  • Understand the interplay between mechanical strain and electronic structure in nanomaterials.

Main Methods:

  • Studied photoluminescence spectra of 4 and 6 monolayer thick CdSe/CdZnS nanoplatelets up to 6 GPa.
  • Employed density functional theory and theoretical modeling.

Main Results:

  • Observed a nearly linear increase in the band gap of approximately 33 meV/GPa.
  • The band gap increase was significantly slower compared to bulk CdSe and CdSe quantum dots.
  • Identified core hardening due to lattice mismatch strain as the cause.

Conclusions:

  • Strain-induced hardening of the CdSe core significantly impacts the electronic structure.
  • Core-shell nanoplatelets exhibit unique pressure-dependent optical properties distinct from bulk materials.
