A method of synthesis of two-dimensional (2D) nanoparticles comprises combining a first nanoparticle precursor and a second nanoparticle precursor in one or more solvents to form a solution, followed by heating the solution to a first temperature for a first time period, then subsequently heating the solution to a second temperature for a second time period, wherein the second temperature is higher than the first temperature, to effect the conversion of the nanoparticle precursors into 2D nanoparticles. In one embodiment, the first nanoparticle precursor is a metal-amine complex and the second nanoparticle precursor is a slow-releasing chalcogen source.

The various embodiments herein provide a light emitting concrete composition and a method of synthesizing a light emitting concrete structure. The light emitting concrete composition comprises light-emitting pigments. The light emitting pigments include a titanium powder, a sulphide powder and resins, cement, sand, gravel and water. The method of synthesizing a light emitting concrete structure comprises preparing slurry. The slurry is prepared by mixing sand, gravel, cement and water. Further, a light emitting pigment mixture is prepared. The light emitting pigment mixture is prepared by mixing a titanium powder, resins and a sulphide powder. The light-emitting pigment mixture is added to the slurry. The slurry is molded by adding the slurry in molds. The molds are further kept at a temperature of 15-20 C. for at least 12-14 hours. The slurry is cured at a temperature of less than 30 C. for 24 hours.
