Abstract
AbstractIn this work, we report on the synthesis of CdTe nanocrystals (NCs) by using of two different saturated long‐chain capping ligands, oleic (OA) and myristic acids (MA), and investigate their influence on the nanocrystals optical properties. The main goal of our study is to identify the ligand that allows slowing down the growth rate of the NCs after nucleation, in order to obtain small enough nanocrystals emitting in the blue‐green part of the optical spectrum. Our results show clearly that oleic acid allows a good control on the CdTe NCs growth, finally leading to a fine‐tuning of the NCs size‐dependent emission from the green to the yellow part of the spectrum. Instead, a faster reaction kinetics, which arises in a lower possibility to produce small NCs emitting in the green part of the spectrum, was noticed using myristic acid.
