ABSTRACT
Polyvinyl pyrrolidone capped Zn1-xMnxS (0 ≤ x ≤ 0.1) nanocrystals have been synthesized using wet chemical co-precipitation method. Crystallographic and morphological characterization of the synthesized materials have been done using X-ray diffraction and transmission electron microscope. Crystallographic studies show the zinc blende crystals having average crystallite size approx. 3 nm, which is almost similar to the average particle size calculated from electron micrographs. Atomic absorption spectrometer has been used for qualitative and quantitative analysis of synthesized nanomaterials. Photo-catalytic activity has been studied using methylene blue dye as a test contaminant. Energy resolved luminescence spectra have been recorded for the detailed description of radiative and non-radiative recombination mechanisms. Photo-catalytic activity dependence on dopant concentration and luminescence quantum yield has been studied in detail.

Figure 1: XRD pattern of Zn0.9900Mn0.0100S nanocrystals.

Mentions: Broad XRD patterns have been recorded for all the synthesized Zn1-xMnxS samples, Figure 1 shows one such X-ray diffractogram recorded for Zn0.9900Mn0.0100S. It is clear from the diffractogram that synthesized samples crystallize in zinc blende structure with the planes at {111}, {220}, and {311}, respectively. Recorded diffraction peaks are broadened due to the nanocrystalline nature of particles. Average crystallite size calculated from the recorded XRD patterns is approx. 3 nm.
