Abstract

The successive ion layer deposition reaction (SILAR) technique has been applied to CdSe based systems to develop Type 1 heterostructures . In such structures, the CdSe core is covered by wider band gap semicondutors to improve the emission properties. Cores of different dimensions has been synthesised and two different shell structures have been addressed. The obtained particles have been characterised by TEM technique, while UV-Vis absorption and photoemission spectroscopy were used to characterise the optical properties of the particles in the colloidal solution. The obtained particles were also introduced in a ZrO₂ sol-gel matrix to fabricate photoluminescent waveguides, which were characterised also by spectroscopic ellipsometry.
