Semiconductor nanoparticles of cadmium chalcogenides are known to exhibit pronounced thickness-dependent $E_0$ series of exciton transitions at the $\Gamma$ point of the Brillouin zone (BZ). In this work, we report an experimental evidence for high-energy series of exciton transitions, which originates from BZ points different from the $\Gamma$ point, in the family of cadmium chalcogenide quasi-2D nanoplatelets (NPLs). Intensive UV absorption bands demonstrating a pronounced size effect are…

TLDR
Photochromic systems containing two-dimensional CdSe nanoparticles (colloidal quantum wells) and photochromic compounds of the thermally relaxing chromene and thermally irreversible diarylethene classes in solutions were found to exhibit modulation of emission of two- dimensional nanoparticles in accordance with thephotochromic transformations of compounds due to Förster resonance energy transfer.
