Abstract

The robust, non-cytotoxic, silica-coated method was used to prepare CdSe quantum dots with efficient photoluminescence. Varying the amount of water and ammonia in the microemulsion also affected the silica shell thickness, since this altered the aqueous domain size. High-resolution TEM (HRTEM) images of SiO₂/CdSe illustrated the crystal lattice fringes of CdSe in the silica nanoparticles. Polyethylene glycol (PEG) was introduced to the SiO ₂ surface, to demonstrate the ease of SiO₂ functionalization.
