“…However, it should be worthwhile to note that the MS fi lms of the reported data were synthesized differently in each case. Therefore, it is not reliable to compare the conductivity and charge carrier mobility of the MS fi lms deposited by the proposed protocol to those reported [33] R denotes the previously reported data.…”

5739wileyonlinelibrary.com deposition method, which is facile, benign, and which can deposit a uniform MS thin fi lms is highly desirable. Although various available techniques such as chemical vapor deposition, [ 9,10 ] atomic layer deposition, [ 11,12 ] molecular beam epitaxy, [ 13,14 ] electrodeposition, [ 7,15 ] successive ionic layer adsorption and reaction, [ 16,17 ] vapor sublimation, [ 18 ] etc., are able to produce thin fi lms of MS, they lack generality or need sophisticated instrumentation, and are complicated. In this context, chemical bath deposition is inarguably the simplest method for thin fi lm deposition. Generally, a suitable complexing agent and pH regulating agents are added in order to avoid spontaneous precipitation in an aqueous bath, which makes the process complicated due to extremely critical optimization for concentration of complexing agents and pH adjustment for an individual MS case. [ 4,[19][20][21][22] As a result, development of MS fi lms by solution-based method has often been a case of trial-and-error with poor reproducibility, which remained as an unexplored research fi eld yet in material science and technology. In order to tackle the above problems in aqueous solution, the fi lm deposition reaction is carried out in ethanol solution without the use of any complexing and/or pH-regulating agents. This protocol relies on dissolution of metal salts and thioacetamide in ethanol and heating the solutions at 70 °C. Although very few reports on MS fi lm deposition from nonaqueous solution has been reported, [ 23,24 ] no general protocol is available that can be applied overall to deposit all variety of MS thin fi lms under similar conditions with good reproducibility. The proposed protocol is extremely simple and general, which can lay simple guidelines to fabricate almost all types of metal sulfi des uniformly over all area of the substrate, provided that the corresponding metal salts are soluble in ethanol. The as-deposited MS fi lms are highly crystalline even without thermal treatment. Interestingly, the fi lms can be directly grown on variety of conducting as well as non-conducting substrates such as glass, plastic, fl uorine doped tin oxide (FTO), Ti-foil, carbon paper, Whatman fi lter paper, etc., which can be of great technological importance. As an example of potential application of these thin fi lms, we demonstrate the use of NiS fi lm deposited on fl exible plastic substrates as FTO-free dual-functioned (electronic support + electrocatalytic) counter electrode in dye-sensitized solar cells Revisiting Metal Sulfi de

“…They grow at lower temperatures and come in three structural shapes: zinc-blende, rock-salt and wurtzite. The rock-salt MnS structure is more stable than both β and γ-MnS and can irreversibly transform into a stable form of rock-salt structure at high temperatures of 100–400 °C [ 13 , 14 , 15 , 16 ], accounting for the unique chemical properties displayed by metastable MnS as compared to the stable phase [ 8 ].…”

The necessity to develop renewable energy resources that are highly durable and flexible with superior energy density and capacitance ability has attracted considerable interest in the field of solar cell research. Semiconducting compound materials that are easily available, hazard-free and cost-effective are emerging as potential solutions to tackle this challenge. Herein, we present multiple molecular precursors used to grow manganese sulfide nanoparticles through a proficient one-step heat-up approach. For all of the tested samples, the X-ray diffraction peaks correspond to a γ-MnS hexagonal wurtzite structure. UV-Vis spectroscopy yielded absorption wavelengths of 359–420 nm and band-gap energies of 3.78–4.0 eV. Photoluminescence analysis shows characteristics of red and blue shift from 451–602 nm. High-resolution transmission electron microscopy (HRTEM) and selected-area electron diffraction (SAED) reveal a narrow size distribution with nanosticks and large contact areas, which are critical for improved catalytic performance. The current study provides an improved pathway to a well-grown and uniform nanocrystal structure for applications in energy devices.

“…The -MnS form crystallizes in cubic structure and it is an antiferromagnetic material with a Neel temperature at 150 K. The -MnS form crystallizes in zinc blende structure and -MnS form has the wurtzite structure [1][2][3][4]. MnS is a wide band gap semiconductor that has a potential use in short wavelength optoelectronic devices such as in solar selective coatings, solar cells, sensors, photoconductors, optical mass memories as well as like a blue green light emitter [5][6][7][8][9][10]. It is reported that doping is one of the common methods to alter electrical, optical and magnetic properties of nanomaterials and hence the researchers have doped materials like MnS and ZnS with metal ions [11][12][13][14].…”

Manganese sulfide (MnS) is a wide band gap material which has the potential use in short wavelength optoelectronic devices, photo-catalysis, solar cells etc. To alter the various properties of MnS nanomaterial, it was decided to add magnesium (Mg) as the dopant. Mg-doped MnS nanomaterial was synthesized by microwave-assisted solution method. From XRD and HRTEM studies, the crystallite size of the sample was estimated. Optical characterization of the sample was done by recording the UV-visible-NIR spectrum. The luminescent properties of Mg-doped MnS nanomaterial was analysed. The functional groups of the sample was found by FTIR studies and thermal stability was checked by TG/DTA studies. Also, Mg-doped MnS nanomaterial was characterized by SEM, EDAX and SAED studies.
