Chirality in luminescent Cs₃Cu₂Br₅microcrystals producedvialigand-assisted reprecipitation

Abstract

Herein we report new chiral luminescent Cs3Cu2Br5 needle-like microcrystals and the analysis of their optical properties and the effect of the ligand structure on the tranfer of chirality.

Ligand induced chirality in In2S3 nanoparticles

“…20 In particular, in the case of semiconductor nanoparticles, some authors have focused their attention predominantly on inorganic nanoparticles, considering the nanoparticle size, 21,22 shape [23][24][25] and structure 14,26 (core-shell systems characterised by different band alignment types and shell thicknesses). Instead, others have been more focused on the effect of the ligand, involving the ligand structure, [27][28][29] binding modes and chemisorption equilibrium. 28,30,31 Indium sulfide is a III-VI type wide band gap semiconductor material, largely investigated due to its high environmental stability combined with its potential use as a toxic-metal free semiconductor for a broad range of applications in optoelectronics, including photocatalysis, 32 photovoltaics 33 and photodetectors.…”
