• Resumen

  • First-year undergraduate students prepare bulk and nanometer-sized cadmium sulfide clusters within water-in-oil micelles. Particle size is calculated using the effective mass model. Quantum-size effects are observed by visual analysis and in the absorbance spectrum of the CdS nanoparticle microemulsion. This laboratory experiment provides an effective way to introduce nanotechnology and surfactant chemistry to students in the general chemistry laboratory.
