Silicon nanocrystals (SiNCs) have gained significant interest in recent years due to their intriguing properties that are not exhibited by their bulk counterpart. When dimensions of SiNCs are reduced below the Bohr radius of an exciton in Si (~4.5 nm), they photoluminesce at energies that are tunable by defining SiNC size and surface functionalization. This, in combination with their low toxicity, biocompatibility and elemental abundance of Si, makes SiNCs a promising material for several applications including LEDs, solar cells, sensors and photoluminescent biomarkers.

My research project

Surface functionalization of SiNCs with conjugated π-systems could be promising for applications in electronic devices, because they might offer the possibility of charge transfer from/to the SiNCs or give rise to unforeseen properties. Besides, these surface groups can offer favorable interface to conjugated polymers to form hybrid composites with improved properties. The aim of the project is to design conjugated systems and attach them to SiNC surfaces. Upon successful surface functionalization, SiNCs would be characterized in detail and their application in optoelectronic devices prototyped.
