6. Synthesis and Characterization of PbS Quantum Dots
University essay from Lunds universitet/Kemiska institutionenAbstract : Colloidal semiconductor nanocrystals or quantum dots (QDs) have recently attracted much attention because of their unique electronic and optical properties and potential for a wide range of applications. Near-infrared (NIR) PbS QDs were synthesized using oleic acid (OA) as a surfactant for stabilizing the nanocrystals. READ MORE

7. ZnO nanoparticles : synthesis of Ga-doped ZnO, oxygen gas sensing and quantum chemical investigation
University essay from Institutionen för fysik, kemi och biologiAbstract : Doped ZnO nanoparticles were synthesized by three different methods – electrochemical deposition under oxidizing conditions (EDOC) , combustion method and wet chemical synthesis – for investigating the oxygen gas sensing response. Ga-doped ZnO was mostly synthesized but also In-doped ZnO was made. READ MORE

8. Synthesis and characterisation of ZnO nanoparticles.An experimental investigation of some of their size dependent quantum effects
University essay from Institutionen för materialkemiAbstract : ZnO nanoparticles in the size range 2.5–7 nm have been synthesised by a wet chemical method where ZnO particles were grown in basic zinc acetate solution. The optical band gap increases when the size of the particles decreases. READ MORE

9. Low-temperature synthesis of CdS nanocrystals in aliphatic alcohols
University essay from Institutionen för materialkemiAbstract : In this report a novel low temperature synthesis approach of CdS nanocrystals is described starting from well known precursors, Cd(SA) and TOP-S, in a ligand system of aliphatic long chain alcohols. A one-pot synthesis approach is applied using a laboratory microwave heating source. READ MORE

10. Synthesis and investigation of an oxygen-evolving catalyst containing cobalt phosphate
University essay from Institutionen för fysik, kemi och biologiAbstract : The experimental section in this thesis was based on the work of Kanan, M.W, et al reported in Science in December of 2008. A catalyst containing cobalt and phosphate was synthesized and used to decompose water into oxygen and hydrogen. This was done at nearly neutral pH. READ MORE
