The NSL is offering 2 30013 projects in 2014 for 3rd year chemistry majors.
Project 1 – ZnO Nanocrystals for solution-processed LEDs and solar cells
Description: Zinc oxide nanoparticles (ZnO NPs) are increasingly used as electron-transport layers in a wide range of solution-processed devices such as solar cells, LEDs, and transistors. The synthesis of ZnO NPs is done via hydrolysis of Zn2+ salts (typically zinc acetate) using a base (typically KOH or tetramethylammonium hydroxide, TMAH). This project will investigate the effects the choice of base, synthesis parameters, and post-synthesis processing have on the resultant ZnO NP properties and their performance in electronic devices.
Time commitment & location: The project will require 1-3 days per week of work at Melbourne University to work on the synthesis and characterisation of the ZnO NPs. Devices will be fabricated at CSIRO in Clayton on a weekly or fortnightly basis and there is a possibility the student can participate in this process subject to travel and access arrangements.
Suitable students: The project is suitable for a student with an interest in inorganic chemistry, nanotechnology, and/or device physics. Prior knowledge of device physics is NOT required.
Project 2- Near Infra Red emitting Semiconductor Nanocrystals for Bio-imaging
Description: Fluorescent nanocrystals (NCs) have been utilised in biological and life science research for assay detection as well as in-vitro imaging for their unique optical properties. We have recently developed a technology at Bio21 for conjugating visible emitting NCs to biomolecules. This project involves exploring various synthetic routes to expand our current NC library to near infra-red emitting particles. The resultant NCs then will be functionalised in preparation for bioconjugation.
Time commitment & location: The project will require 1-3 days per week of work at Melbourne University.
Suitable students: The project is suitable for a student with an interest in synthesis, surface chemistry, nanotechnology, and bio applications.
