Microwave-assisted synthesis and characterization of undoped and manganese doped zinc sulfide nanoparticles

“…These values agree well with that found previously by EXAFS in Zn 1−x Mn x S nanoparticles [46,47,48] and nanowires [45]. Note also that Mn-S distance is close to that in bulk zinc blende MnS (R(Mn-S)=2.42 Å [39]). The difference between the two distances agrees well with the difference in the ionic radii for two ions in a tetrahedral environment: the ionic radius of Zn 2+ (IV) is 0.60 Å, while that of Mn 2+ (IV) is 0.66 Å [49].…”

“…The Rietveld refinement procedure was used to extract the values of the lattice constant a and the average size of crystallites d from X-ray diffraction patterns, which are reported in Table 1. The lattice constants are in the range of a=5.406-5.411 Å with the average value of 5.408(5) Å, which is close to that in the bulk zinc blende ZnS (a=5.41 Å [37,38]) but is smaller than that in zinc blende phase of MnS (a=5.59 Å [39]). The average sizes of nanocrystallites are in the range of d=6-9 nm.…”

Effects of natural organic matter (NOM), metal-to-sulfide ratio and Mn2+on cadmium sulfide nanoparticle growth and colloidal stability

“…In samples absent in SRFA, the first-shell S atoms were fitted at 2.42 Å, an interatomic distance shorter than a typical Cd-S distance in a hawleyite crystal and rather corresponding to the Mn-S distance usually found in rambergite (γ-MnS, ICSD ref. code 643455), 139 thus supporting the hypothesis of a crystal lattice contraction in CdS caused by Mn incorporation. In the second shell of these samples, the Mn-Mn and Mn-Cd paths were fitted at 3.95 Å and 4.12-4.16 Å, respectively.…”

Rudashevskyite, the Fe-dominant analogue of sphalerite, a new mineral: Description and crystal structure

“…Well-known sphalerite-wurtzite polytypysm is a characteristic feature of FeS-ZnS-MnS solid solutions. Pure MnS may crystallize in both polytypes, hexagonal rambergite-2H (Kalinowski 1996) and synthetic cubic MnS-3C (Mehmed and Haraldsen 1938). Cubic sphalerite-type FeS is known but it is metastable.…”
