ABSTRACT = {Amongst the promising transition-metal chalcogenides, nickel tellurides at nanoscale are widely recognized for their distinctive structural and electronic properties and multifunctional behavior that enables their use in a broad range of modern technologies. Nickel tellurides with customized properties can be produced by various techniques that include hydrothermal and solvothermal routes, being the most popular, etc. The present findings are based on direct synthesis of phase-pure nickel telluride, with varying nonstoichiometric compositions. The progress of the experiment was assessed by UV-visible spectroscopy, and the so-synthesized samples were named as DB-4 (NiTe<sub>2</sub>), DB-6 (Ni<sub>2</sub>Te<sub>3</sub>), and DB-7 (NiTe). The formation of different near stoichiometric nickel telluride(s) was finally confirmed by X-ray diffraction measurement. The diameters in the range of about 8–14.1 nm with lattice spacings of about 0.29 nm at the (101) plane was estimated for the so-obtained nanostructured nickel tellurides. X-ray photoelectron spectroscopy (XPS) analysis revealed the elemental composition and chemical states of the nickel telluride. HRTEM and FESEM imaging showed directional clustering possibly due to the magnetic character of the nanoparticles. Magnetic property evaluation showed weak magnetic behavior, indicating it to be ferromagnetic in nature. The black powders were converted to (polyvinyl alcohol) PVA films to realize their low X-band EMI shielding effectiveness (SE) of about 3.1 dB, which showed an increasing trend with percentage filler. Similarly, their thermoelectric data suggest that they are materials that can be tailored for potential applications.},
