Summary on Grant Application Form |
|
The proposal is concerned with the preparation and the characterisation of nanoparticle coated electrodes. It is anticipated that manipulation of the deposition parameters will permit control of the particle distribution. In the initial stages of the project monodisperse metal and semi-conductor Q-particles will be prepared using established methods and analysed. UV-vis spectroscopy will be the method of choice for characterising the Q-particles. Conducting substrates will be functionalised using organosilanes and/or thiols. The Q-particles will then be deposited on these prefunctionalised surfaces. The influence of deposition potential, pendent group density and colloid stabiliser on the nanocrystalline film architecture will be investigated. High resolution scanning electron microscopy, carbon replication transmission electron microscopy and scanning probe microscopy techniques will be employed to image the modified electrode surfaces.The optoelectronic properties of the modified films will be analysed using electrochemistry, the use of a liquid top contact negates any problems associated wit the deposition of a solid contact. To circumvent pinhole problems, the electrochemical characterisation will be limited to photoelectrochemical investigations of substrates modified with semiconductor nanoparticles. The influence of particle size and spacing on photostimulated charge transfer processes will be investigated.
