Abstract
Structural and optical characteristics of manganese doped cadmium sulfide nanoparticles prepared by in situ chemical synthesis using biocompatible Na-alginate biopolymer as a template is reported.
Highlights
An important part of modern nanoscience and nanotechnology is the investigation of new materials composed of a polymer matrix lled with semiconductor nanoparticles.[1,2] These types of nanocomposites combine characteristic optical, electrical, magnetic or catalytic properties of semiconductors with the chemical stability and processability of polymers
We report on structural and optical characteristics of manganese doped cadmium sul de nanoparticles prepared in aqueous solution by an in situ chemical synthesis using biocompatible Na-alginate biopolymer as a template
Fourier transform infrared (FTIR) analyses of the starting biopolymer, Cd2+ crosslinked alginate and cadmium sulfide (CdS)-alginate nanocomposite con rmed the interaction between the nanoparticles and the biopolymer (ESI, Fig. S1†)
Summary
A macromolecule extracted from brown marine algae, is a block-copolymer of (1,4)-linked b-Dmannuronic and a-L-guluronic (G) acids.[15]. We report on structural and optical characteristics of manganese doped cadmium sul de nanoparticles prepared in aqueous solution by an in situ chemical synthesis using biocompatible Na-alginate biopolymer as a template It will be studied how the distorted crystal eld surrounding the Mn2+ ions affects the CdS:Mn-alginate nanocomposites photoluminescence regarding their potential use in bioimaging, since particular photoluminescent characteristics of the nanocomposites coupled with the biocompatibility of alginate open up a possibility of application of the prepared materials as uorescent substrates for tissue imaging in the NIR domain.[38]
