“…For example, in [35,36], the PL measurements performed in Mn-doped ZnS samples obtained by milling Zn, Mn and S did not evidence the characteristic emission at ~ 580 nm, which infers that the samples were not properly doped. In [37], any luminescence measurement was shown and in [38], the comminution of commercial microsized ZnS:Mn 2+ samples induced only a slight improvement in PL spectra.…”

“…Few reports can be found in the bibliography dealing with the synthesis of Mndoped ZnS by ball milling methods [35][36][37][38]. In [35] and [36] Mn-doped ZnS samples were obtained by milling Zn, S and Mn powders.…”

“…Tolia et al [37] synthesized by a mechanochemical method doped sulfide samples from zinc acetate, manganese acetate and sodium sulfide. Finally, Hamaguchi et al [38], starting from commercial microsized ZnS:Mn 2+ , obtained ZnS:Mn 2+ nanoparticles by ball milling in a solvent medium. Nevertheless, in this work, a comminution process and not a mechanochemical one was carried out, since no chemical changes were induced during milling, but only a reduction of the particle size.…”

The mechanochemical process denoted as mechanically-induced self-sustaining reaction was successfully applied in obtaining Mn-doped ZnS samples with a Mn content between 0 and 5 mol%. The process consists in milling Zn/Mn/S powder elemental mixtures with the appropriate stoichiometry, which promotes after approximately 80 min the induction of a combustion reaction. The doping level was properly adjusted by controlling the atomic ratio of the starting mixture. A complete characterization of samples was carried out, including X-ray diffraction, high-resolution transmission electron microscopy, selected area electron diffraction, energy dispersive X-ray spectroscopy, Raman spectroscopy, diffuse reflectance UV-Vis spectroscopy and emission and excitation photoluminescence measurements. A wurtzite structure, in which Mn 2+ replace Zn 2+ , was obtained with a nanometric character. The photoluminescence of samples showed the characteristic Mn 2+ 4 T1-6 A1 emission that was highly dependent on the doping level. The maximum luminescence efficiency through the ZnS excitation was found for a doping value of 1 mol%. The photoluminescence showed virtually no contribution from the host emission, which confirmed that samples were properly doped.

“…The special interest on ZnS:Mn is due to its high photoluminescence efficiency and stability at ambient temperature. These are considered as an ideal candidate material for fluorescence bio-labeling due to its long luminescence life time [9][10][11]. Such nanomaterials have been applied to light emitting diodes, photovoltaic devices, lasers, sensors, phosphors in displays and also in diagnostics, and photocatalysis [12][13][14][15][16].…”

“…Nanoparticles with quite well optical properties were achieved. 7,8) The ball-milling method is a simple method and it would be suited to the mass production. Since Cd and Se are harmful elements to human bodies and CdSe nanoparticles require rigorous control of particle size under 10 nm to tune the luminescence color and the peak wavelength, 9) ternary sulfide based phosphors such as Ba 2 ZnS 3 :Mn, SrGa 2 S 4 :Eu, and BaAl 2 S 4 :Eu were focused as the alternative phosphor nanoparticle materials which does not include harmful elements.…”

Conventional phosphor materials are doped ternary or quaternary compounds; hence it would be difficult to prepare those nanoparticles by build up methods. Ba 2 ZnS 3 :Mn, SrGa 2 S 4 :Eu, and BaAl 2 S 4 :Eu nanoparticles were prepared by a break down method, namely ball-milling method. Transmission electron microscopy (TEM), and TEM-energy-dispersive X-ray spectroscopy (EDX) measurements showed several-nanometer-size stoichiometric and dispersed nanoparticles were achieved. The annealing was performed after the milling for those particles to cure the mechanical damages. The annealing in a vacuum at around the calcination temperature of starting materials showed the cured photoluminescence (PL). ZnO-coating was performed and the uniform coating layer of the thickness about 10 nm was formed on the phosphor nanoparticles. The ZnO-coated nanoparticles exhibited an improved stability in PL.
