Abstract

Bottom-up approach to fabricate dislocation-free luminescent γ-MnS nanosaws via CVD that can be used as anode material for Li-ion batteries.

Manganese Sulfide (MnS) Nanocrystals: Synthesis, Properties, and Applications

“…CVD has been employed to synthesize γ-MnS 1D nanosystems with a peculiar comb-shaped morphology [10]. MnCl and sulfur powder (Mn:S = 1:3) were used as precursors and AuCl 3 treated (001) silicon was used as a substrate.…”

“…Another 1D nanoheterostructure involving γ-MnS nanowires has been synthesized to improve the performance of 1D γ-MnS nanosystems as electrode materials for Li-ion batteries [11]. The preparation method is similar to that used by the same authors to prepare γ-MnS nanosaws [10], but the used Mn:S ratio of 1:3 and methane gas(partial flow = 5 sccm) added to the argon flow in the furnace. The products are nanowires comprising an elongated γ-MnS nanocore conformally coated with graphitic carbon and with hexagonal cross section (see Figure 4).…”

“…The optical properties of CVD-synthesized γ-MnS nanosaws (length ~25 μm in the [0110] direction, width = 100-350 nm) were analyzed in detail in Ref. [10]. The PL spectrum of the nanosaws was recorded at temperature between 10 and 300 K after excitation at 325 nm.…”

“…The optical properties of MnS have also raised considerable interest in protobiology since it is deemed to have played a key role (along with ZnS in mixed haloes formed around primeval sub-aerial hot springs) in the prebiotic photosynthesis development, thanks to its ability to photoreduce CO 2 [7]. More recently, interesting energy-related applications have been demonstrated, where MnS was employed as an electrode material in Li-ion batteries [10][11][12][13] and as a supercapacitor material [14,15]. These interesting properties and promising applications have raised considerable attention and research on small MnS particles can be considered to begin with the submission of three papers within the middle 6 months of 2001.…”

Dielectric shell modulated plasmonic crystal for novel light absorption meta-surface

“…Currently, the origin confined field in the polymer or silica spheres was demonstrated to be extracted into the higher dielectric nanocavities [13,14]. High-index dielectric resonators have been recently risen to prominence in the nanophotonics toolkit for control of light in the near-field [15][16][17][18][19].…”
