The present disclosure relates to a nanoparticle containing at least one metal sulfide nanocrystal having a surface modified with a carboxylic acid, wherein the carboxylic acid has at least one aryl group. The present disclosure also describes a method of preparing the nanoparticle, the method consisting of: (a) providing a first solution having a first organic solvent, and a non-alkali metal salt and a carboxylic acid dissolved therein, wherein the carboxylic acid has at least one aryl group; (b) providing a sulfide material; and (c) combining the first solution and the sulfide material to form a reaction solution, thereby forming a nanoparticle containing at least one metal sulfide nanocrystal having a surface modified with the carboxylic acid, wherein the carboxylic acid has at least one aryl group.
