The Development of Novel Optical Materials Via Quantum Dot-Doped Sol-Cel Hosts.
Abstract
The research performed on this grant began with the study of CdS quantum dots in a sol gel host as an enhancement to semiconductor-doped glass systems. The CdS dots were synthesized via inverse-micellar chemistry, which is shown to be capable of compositionally-homogeneous semiconductor colloids. The results involving synthesis and optical characterization of solution-derived, quantum-dot-doped materials is discussed, including preliminary results on transition-metal doping of CdS dots. The final year of the grant was focused on the growth of nanostructures on glass substrates by pulsed-laser deposition (PLD). A series of thin films composed of binary through quaternary II-VI semiconductors were deposited on silica substrates. The work includes deposition from stoichiometric PLD targets as well as targets which were alternated to achieve the desired stoichiometry. The films were characterized by absorption spectroscopy.
