“…It is found that the MnS film deposited on the glass substrate is of poor crystallinity and amorphous characteristics. A similar amorphous nature was reported by other workers for the MnS thin film growth on to glass substrate by CBD [5,11,17] and SILAR [19] method. Figure 4b shows the XRD pattern of annealed MnS thin film in the range of 2θ angle from 10° to 60°.…”

“…This decrease of band gap may be attributed to the presence of unstructured defects and the increase of density of localized states [21]. Our obtained E g values are found in good agreement with the band gap of MnS films deposited by other techniques [5,9,11,19]. The variations of optical band gap with different film thicknesses are given in table 2.…”

“…It is known that the MnS has three crystalline forms: thermodynamically stable α-MnS phase with an octahedrally coordinated rock salt structure, pink metastable tetrahedrally coordinated β and γ-MnS with zincblende and wurtzite structures respectively [10]. It has been found that β and γ-MnS can transform irreversibly to the stable α-MnS in the range of 373 to 673 K [11,12]. Various methods so far adopted for the preparation of MnS thin films, such as molecular-beam epitaxy (MBE) [13], thermal vacuum evaporation [4,10], radio frequency sputtering [14,15], microwave irradiation [16], chemical bath deposition (CBD) [5,9,17], SILAR method [18] and solvothermal method [19].…”

Manganese sulphide (MnS) thin films have been deposited onto glass substrate by a low cost spray-pyrolysis technique at 220 °C. The as-deposited MnS thin films have been characterized using scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy, atomic force microscopy (AFM), X-ray diffraction, UV visible spectroscopy and photo electrochemical (PEC) measurement. The SEM and AFM images showed that the MnS thin films were well covered onto the substrate surface. The as-deposited raw thin film was found to be amorphous in nature and perfectly crystalline phase after annealing the sample. Optical band gap of the MnS thin films was found to vary from 3.1 to 3.21 eV and the band gap decreases with the increase in film thickness. Optical constants such as refractive index, extinction coefficient have been evaluated using reflectance and absorbance data.

“…MnS thin film production has been carried out by using several deposition techniques, such as molecular beam epitaxy, [33][34][35][36][37] chemical vapor deposition, [38,39] atomic layer deposition (for ZnS:Mn films), [40] thermal vacuum evaporation, [41][42][43] microwave hydrothermal, [44] radio-frequency sputtering, [45,46] and chemical bath deposition (CBD). [24,26,[47][48][49][50][51] With the exception of CBD, all of these techniques require a vacuum, or sophisticated instruments, which is not conducive to the cost-effective deposition of uniform films over large areas of substrate. Films that have been prepared using CBD are often found to be of an amorphous nature and subsequent annealing is needed in order to obtain a crystalline film.…”

A spray-based technique, originally developed for the production of semiconductor nanocrystals, is utilized for the preparation of high-quality nanocrystalline thin films, as demonstrated with manganese sulfide. The films are formed by the use of pneumatic-assisted thermospray or pneumatic nebulizers. Our simple, low-cost, and low-temperature process results in a dense and phase-pure grain structure. The concepts and benefits of this technique are described and discussed. The film characteristics show dependence on the experimental parameters, in particular the rate of solvent vaporization. Three alternative film formation mechanisms are suggested for cases with varied experimental conditions.
