Abstract:
A method of making a colloidal suspension of photoluminescent porous silicon particles involves removing a layer of porous silicon from a substrate using a first ultrasound energy to form a first plurality of porous silicon particles in a colloidal suspension. The first plurality of porous silicon particles in the colloidal suspension are exposed to a second ultrasound energy to reduce the size of the first plurality of porous silicon particles in the colloidal suspension, thereby forming a second plurality of porous silicon particles in a colloidal suspension, wherein the second plurality of porous silicon particles are in the amorphous phase.
