Abstract

A simple method for the preparation of hybrid luminescence and rodlike CdS nanoclusters/poly (propylene-grafted-(2-methylacrylic acid 3-(bis-carboxymethyl amino-2-hydroxy-propyl ester) (GMA-IDA))) fibers, by plasma induced method following chemical deposition method, is presented in this study. GMA-IDA chelating groups which are grafted onto the poly(propylene) fibers are the coordination sites for chelating Cd +2, on which nano-sized CdS nanocrystals grew. TEM observations demonstrate that the mean diameter of CdS nanocrystals inside the poly(PP-graft-GMA-IDA) fibers alters from 2 nm to 8 nm at various concentrations of S 2- solution. Additionally, SEM presents that the CdS nanocrystals on the surface have rod-like structure. The UV-vis absorption spectra provide the information of the absorption edges, band-gaps, and average diameter of CdS nanocrystals, the results of which are coincidence with the TEM observations. Furthermore, the photoluminescence (PL) shows the maximum peaks are 495 nm, 571 nm, 657 nm, and 675 nm corresponding to the mean particle sizes 2.6 nm, 3.5 nm, 4.8 nm, and 7.7 nm, respectively, at an excitation wavelength of 366 nm.
