“…ZnS and CdS, as group II-VI semiconductor materials with wide band gap, are commercially used as the phosphors in thin-film electroluminescent devices, solar cells, and other optical electronic devices [8][9][10][11]. Their nanocomposites are being extensively studied due to their good semiconductor characteristics.…”

“…The d‐spacing values and relative intensities of the peaks representing cubic structure of ZnS matched the Joint Committee on Powder Diffraction Standards (JCPDS) data (card no. 05–0566) . Furthermore, the broadening of diffraction peaks confirmed that the obtained crystallites were of nano size.…”

Luminescence technology has been improved with the help of semiconductor nanoparticles that possess novel optical and electrical properties compared with their bulk counterpart. The aim of this study was to design semiconductor nanocrystals in their pure (ZnS) or doped form (ZnS:Mn) with different concentrations of Mn ions by a wet chemical route stabilized by ethylenediamine tetra-acetic acid (EDTA) and to evaluate their luminescence properties. The nanocrystals were characterized by physicochemical techniques such as X-ray diffraction (XRD), High-resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SEAD), EDS, and ultraviolet (UV)-visible light and photoluminescence (PL) studies. These results showed the presence of cubic phase and spherically shaped nanocrystals. A blue shift with respect to their bulk counterpart was observed. PL emission spectra were observed with a fixed blue peak and the yellow-orange bands were red shifted towards the red region under the same excitation wavelength. The orange-red bands were attributed to the radiation transition of electrons in 3d5 unfilled shells of Mn ions [ T ( G)- A ( S)]; the ZnS matrix varied with Mn concentration. Shift and increase in the intensity of the PL and absorption bands were observed with increase in Mn content. The study showed that Mn -doped ZnS nanocrystal emission bands can be tuned from the yellow-orange to the red regions under a controlled synthesis process and could be used as promising luminescent emitters in the biology field upon functionalization with suitable materials. Further studies on construction with various other materials will be useful for practical applications.

“…One-dimensional nanomaterials have attracted a great deal of attention owing to their potential applications in nanoelectronics and optoelectronics [1][2][3] since first discovery of carbon nanotubes. ZnO, with wider direct band-gap energy of 3.37 eV and larger exciton binding energy of 60 meV [4][5][6], is a very attractive material for optoelectronic applications [7].…”
