“…Indeed, these ratios stay essentially the same yet the CuS is no longer present in the XRD pattern supporting the claim that Cu inserts into the MnS lattice. In other words, this observation refers that the most amount of Cu species was incorporated in MnS lattice forming CuMnS solid solution [29].…”

“…(v) Increasing bath temperature led to an increase in the calculated crystallite size with subsequent increase in the "c/a" ratio of the as-synthesized materials as demonstrated in Table 1. The crystallite sizes of different films were calculated using the Scherrer formula [29]. This increase could be accredited to the difference between the ionic radii of both Cu and Mn cations.…”

Highly transparent crystalline CuMnS thin films were deposited on the glass substrate by uncomplicated and low-cost chemical bath deposition (CBD) method at different bath temperatures (50-90 °C). The structural, optical, electrical properties of as-synthesized CuMnS thin films have been investigated. The effect of bath temperature on the structure and morphological properties of CuMnS thin films had determined using XRD, SEM, and EDAX analyses. The prepared thin films at 50 °C and 90 °C consisted entirely of nanocrystalline CuS/MnS composite and CuMnS solid solution, respectively, with hexagonal structure. The results confirm that the crystallite size increased with increasing the bath temperature due to the incorporation of Cu species in the MnS lattice. Copper-manganese sulfide thin films have lesser particle sizes at different bath temperature as shown in SEM images. However, it shows spherical and rod-like structure with little agglomeration. EDAX analysis indicates that the deposited thin films contain Cu, Mn, and S ions without any impurities confirming their purity. UV-Vis-NIR, spectral, and electrical DC measurements were carried out to describe the optical and electrical characteristics of the as-synthesized thin films. UV-Visible spectroscopy shows red shift in the optical band gap with different bath temperatures. The electrical conductivity of different films with increasing the temperature from 298 to 473 K was determined. However, the increment in the bath temperature resulted in an increase in the conductivity of films. This increase could be credited to the film density and shadowing effects. The as-deposited films can be predictable to be useful in sunscreens, solar cells, and electro-optical devices.

“…Manganese sulde (MnS), a p-type semiconductor, has been used for sensing, magnetic resonance imaging (MRI) electrochemical water oxidation, lithium-ion batteries, and photocatalysis because of its excellent optical and electrical properties. [24][25][26][27][28][29] However, its biological applications are sparse in the literature. In addition, the consequence of surface functionalization of MnS NPs and the subsequent appearance of novel optical properties have also not been studied yet.…”

“…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]. Dae Sung Kim et al have synthesized Cd-doped -Mns nanowires by the chemical vapor deposition.…”

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.
