Capping Ligand Influence on the Structural, Optical and Luminescence Properties of CdTe Nanoparticles Prepared by a Simple Wet Chemical Process

Kiprotich, Sharon; Dejene, F. B.; Onani, M. O. (2019-03)

The nature of the capping ligands used and the strength of their interactions with the surface atoms of the nanoparticles (NPs) impact greatly on the material properties and the stability of the resulting NPs. The structural ...
High luminescent L-cysteine capped CdTe quantum dots prepared at different reaction times

Kiptotich, Sharon; Onani, M. O.; Dejene, F. B. (2017-07)

This paper reports a facile synthesis route of high luminescent L-cysteine capped CdTe quantum dots (QDs). The effect of reaction time on the growth mechanism, optical and physical properties of the CdTe QDs was investigated ...
The influence of reaction times on structural, optical and luminescence properties of cadmium telluride nanoparticles prepared by wet-chemical process

Kiprotich, Sharon; Dejene, F. B.; Ungula, J.; Onani, M. O. (2016-01)

This paper explains one pot synthesis of type II water soluble L-cysteine capped cadmium telluride (CdTe) core shell quantum dots using cadmium acetate, potassium tellurite and L-cysteine as the starting materials. The ...
