1. A method for making a white-light-emitting material, comprising:

  • forming a solution of CdS nanocrystals;

    reacting a surface of said CdS nanocrystals with a surface-modifying compound to form a solution of surface-dominated light-emitting nanoparticles;

    aging said surface-dominated light-emitting nanoparticles to broaden a light-emission spectrum of said surface-dominated light-emitting nanoparticles to produce a white-light-emitting material, wherein said solution of CdS nanocrystals is formed by an inverse micelle method.
