| The unique optoelectronic properties of organic-inorganic hybrid nanoparticles have opened up extensive opportunities for device applications such as light emitting diodes, photovoltaic cells, displays, etc. However, specific optoelectronic properties, i.e. energy transfer or charge transfer, are required to apply hybrid nanoparticles to these devices. This dissertation investigates the tuning of optoelectronic properties of CdSe nanoparticles capped with various organic ligands and improving their properties for device applications. It also focuses on applying these materials for micropatterning. Chapter 2 details the synthesis of CdSe nanoparticles capped with carbazole-bearing dendrons and their optoelectronic property shift by electrochemistry. In Chapter 3, the preparation of micropatterned CdSe nanoparticle films by photolithography has been introduced. Chapter 4 describes a combined technique in tuning the optoelectronic properties of the micropatterned CdSe NP films as detailed in previous work. Chapter 5 deals with achieving the charge transfer of blends consisting of CdSe nanoparticles and terthiophene units. It details the increasing energy transfer efficiency of the blend by irradiating with UV light. Lastly, a global conclusion highlights the potential and possibilities for further investigations of these materials systems and their various applications. |
