The exfoliation of two dimensional (2D) transition metal dichalcogenides (TMDs) into mono‐ or few‐layers without compromising their semiconductor properties has momentous interest for both point of view; fundamental studies and further implementation in practical applications. Herein, we reported a novel and inexpensive approach for high yield nanosheets from bulk MoS 2 to few layers of strong luminescent MoS 2 nanosheets using Triton X‐100 as a surfactant with tailoring the bulk band gap 1.2 eV to 1.79 eV of few layers of nanosheets after chemical exfoliation process, which can be easily scaled‐up in large quantity. The microstructural results reveal that the exfoliated nanosheets have thickness in the range of few layers and lateral dimension in the range of few hundred nanometers. Our findings may offer a new innovative one setup chemical exfoliation process to design a few layer of MoS 2 nanosheets without suppressing luminescent properties, which is highly desirable for the next generation optoelectronic devices.
