“…occurs and makes the forbidden transition of 4 T 1 -6 A 1 partially allowed, as a result the yellow-orange PL originates from a transition between the 4 T 1 excited state and the 6 A 1 ground state of the Mn 2? ion within a nanocrystalline ZnS lattice (Bhargava et al 1994;Denzler et al 1998;Ren et al 2008;Cao et al 2009).

The studies on luminescent II-VI semiconducting nanomaterials have attracted widespread attention recently, due to their potential applications in optoelectronic and biophotonic devices. Amongst other II-VI semiconductor nanoparticles (NPs), Mn 2? -doped ZnS NPs having large exciton binding energy and wide direct band gap at room temperature have drawn considerable attention for exploring its interesting optical properties. However, in this report, water-soluble Mn 2? -doped ZnS (ZnS:Mn) NPs with Mn 2? concentration varying between 1.5 and 5% (wt%) have been synthesized by chemical co-precipitation method at room temperature. X-ray diffraction (XRD) studies and the analysis of the selected area electron diffraction (SAED) pattern, obtained from transmission electron microscopy (TEM), confirmed the formation of zinc blende structure in all the synthesized samples. The particle sizes of the samples, as obtained from the optical absorption studies, varies between 2.2 and 2.7 nm with the increase of Mn 2? concentration between 1.5 and 5%. The room temperature photoluminescence (PL) emission measurements revealed the presence of yellow-orange emission band in all the Mn 2? -doped samples which is attributed to Mn incorporation in ZnS. The Gaussian fittings of the measured PL spectra of all the samples show the presence of four PL peaks. Amongst the four PL peaks three peaks appeared at 445, 476, and 520 nm in all the samples but the fourth yellow-orange emission peak suffered a red shift from 593 to 600 nm with increasing Mn 2? concentration from 1.5 to 5%. In this report no quenching of yelloworange emission peak is observed up to 5% Mn 2? doping concentration in ZnS. The synthesized water-soluble ZnS:Mn NPs can be further functionalized for using them as biolabels.

Zinc sulfide (ZnS) pure or doped has received remarkable attention because of fundamental properties, versatility and potential for several technological applications as luminescent material. In this study, the local structure and photoluminescence properties of nanostructured Zn1‐xMnxS samples have been characterized. X‐ray diffraction results show that ZnS:Mn samples crystallized completely without the presence of secondary phases and the diffraction patterns correspond to the cubic zinc blende. Theoretical and experimental XANES (X‐ray absorption near edge structure) spectra at Zn K‐edge suggest the incorporation of Mn atoms into the ZnS host and indicate the occurrence of Zn and S vacancies, which are confirmed by EXAFS (extended X‐ray absorption fine structure) fit results. These vacancies can be related to a red‐shift observed in the peak emission of photoluminescence spectrum for ZnS sample, which is centered at ∼ 504 nm. As the Mn content increases, a yellow‐orange emission centered at ∼ 590 nm can be observed besides the blue‐green emission, which is associated with the 4T1–6A1 transition within the 3d shell of Mn2+.

Tuneable luminescence properties of EDTA‐assisted ZnS:Mn nanocrystals from a yellow‐orange to a red emission band

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.
