Tailoring Excitons, Biexcitons, and Trions Dynamics in CdSe/CdS Dot-in-Rod Nanomaterials for Light-Emitting Devices

Abstract CdSe-based core−shell nanomaterials offer the possibility of manipulating exciton dynamics and multi-exciton interactions by controlling the core and shell morphologies. In this context, CdSe/CdS dot-in-rod nanostructure (DiR) has emerged as an interesting class of nanom...

Excitonic Structure in CsPbBr3 Nanocubes,Nanorods, and Nanoplatelets: The Effect of Dimensionality

Abstract We present a theoretical study comparing the excitonic ground-state properties of CsPbBr3 nanocrystals with different dimensionality: nanorods (quasi-1D), nanoplatelets (quasi-2D), and nanocubes (quasi-3D). All three systems are described on an equal footing, by means of...
