This research investigates the synthesis and characteristics of nickel-doped molybdenum disulfide nanostructures. Using a hydrothermal method, powders were produced with nickel concentrations ranging from one percent to seven percent. Analytical assessments, including X-ray diffraction, Raman spectroscopy, transmission electron microscopy, and photoluminescence, evaluated the structural, morphological, and optical modifications caused by the dopant. The addition of nickel preserved the tetragonal crystal structure of the parent compound while systematically reducing the optical energy gap from 1.86 eV to 1.76 eV as doping concentrations increased. Photoluminescence intensity at room temperature improved notably in the doped materials. Furthermore, theoretical calculations using the compact density matrix method modelled the linear and nonlinear optical parameters, showing strong correlation with the experimental results.
Controlling the optical and electronic properties of two-dimensional nanomaterials is essential for advancing electronic and photonic systems. By demonstrating that nickel doping predictably tunes the bandgap and enhances light emission in molybdenum disulfide, this work provides fundamental insights into customising semiconductor nanostructures for light-based components.
The research points to potential applications in optoelectronic technology, which could interest developers of photodetectors, optical modulators, or optical switching components. However, this study remains early-stage laboratory research focusing on material synthesis, characterisation, and theoretical modelling, with no device integration or prototype manufacturing yet demonstrated.

Ni-doped molybdenum disulfide (MoS[Formula: see text] powders at 1%, 2%, 3%, 4%, 5% and 7% of Ni are prepared by the hydrothermal method. Sophisticated analytical studies such as X-ray diffraction, Raman, TEM and photoluminescence (PL) were analyzed to predict their structural, morphological and optical properties. Effects of Ni-doping with MoS 2 on crystalline structure, morphology as well their optical phenomenon were examined in detail. Ni doping on MoS 2 revealed tetragonal crystal structure of the parent compound. A significant decrease in their optical energy gap (from 1.86 to 1.76[Formula: see text]eV) was perceived with Ni doping concentration increment. PL intensity exhibited a considerable improvement with Ni-doped MoS 2 samples at room temperature. From a theoretical viewpoint, the compact density matrix method is applied for Ni–MoS 2 to calculate their linear and nonlinear absorption coefficients as well as refractive index modulations for undoped and Ni-doped samples at the focal points of their corresponding intra-band and inter-band transitions. Observed findings are well correlated with the practical results which prove that Ni–MoS 2 layers are promoters for potential applications in optoelectronic technology.
