Radiative emission from Cu₂ZnSnS₄/ZnSn core/shell nanocrystals

Abstract

The authors experimentally demonstrate that passivation of the Cu2ZnSnS4 nanocrystals by a ZnSn shell can activate the radiative emission.

Ag2ZnSnS4–ZnS core–shell colloidal quantum dots: a near-infrared luminescent material based on environmentally friendly elements

“…Core-shell heterostructures of various binary and ternary QDs that emit NIR PL have been studied in the previous literature. 6,9,10,12 However, core-shell heterostructures of quaternary QDs have rarely been explored 27,28 due to synthetic impediments. Herein, we present the thiol free synthesis of bright tunable NIR luminescent AZTS-ZnS core-shell QDs with controlled growth of shell thickness.…”
