<p>Molybdenum sulfide (MoS₂) has emerged as a prominent two-dimensional material due to its unique electronic, optical, and catalytic properties. However, the controlled synthesis of ultrasmall MoS₂ nanoparticles, particularly in the 3R polytype, remains a challenge for scalable applications. Therefore, in this work a new route to synthesize MoS₂ is presented. From this procedure the nanoparticles are obtained in a colloidal suspension consisting of nanoparticles, which by electron transmission microscopy, are observed as nanometer-scale flake shapes. From the optical absorption spectrum, the direct and indirect band gaps were obtained, giving values of 3.08 and 2.6&#xa0;eV, respectively. Additionally, a size distribution of the particles from their contrast images in a representative region, was performed, and it was found that 78% of the nanoparticles had sizes between 1 and 3&#xa0;nm. On the other hand, studies were performed using X-ray photoelectron and Raman dispersion, where the first demonstrates only the chemical elements involved, while the second matches references in the literature. This synthetic approach provides an efficient and scalable method for producing ultrasmall MoS₂ nanoflakes with potential applications in optoelectronics, catalysis, and energy storage.</p>
