Biography
The research of Dr Celso de Mello Donega is focused on the chemistry and optoelectronic properties of colloidal nanocrystals and heteronanocrystals. Colloidal nanocrystals (NCs) can be regarded as solution-grown inorganic-organic hybrid nanomaterials, as they consist of inorganic particles that are coated with a layer of organic ligand molecules. The hybrid nature of these nanostructures provides great flexibility in engineering their properties. The nanoscale dimensions of the NCs give rise to remarkable size- and shape-dependent properties that can be further engineered by controlling their composition. Moreover, the organic layer opens up the possibility of surface chemistry manipulation, making it possible to tailor a number of properties. These features turn colloidal NCs into promising materials for a number of applications (e.g., optoelectronics, photonics, spintronics, catalysis, solar energy conversion, thermoelectrics, sensors and biomedical applications).
