Colloidal Synthesis

• Immersion of semiconductor microcrystals in glass dielectric matrices.
• Taking a silicate glass with 1% semiconducting phase (CdS, CuCl, CdSe, or CuBr).
• Heating for several hours at high temperature.
• Formation of microcrystals of nearly equal size.
• Typically group II-VI materials (e.g. CdS, CdSe)
• Size variations (“size dispersion”).
