CdSe quantum dots (QDs) were prepared at room temperature by E-beam irradiation of the solution, using ethylene diamine tetraacetic acid as stabilizer. Silica-coated CdSe QDs were made in water-in-oil microemulsion, while amino groups were introduced synchronously onto the nanoparticles by copolymerization of 3-aminopropyl- trimethoxysilane and tetraethyl orthosilicate. The results of TEM imaging, fluorescent spectroscopy and photostability tests show that the QDs are of uniform spherical size (200(8 nm), monodispersity, and high fluorescence and photostability.
