Quantum Dots (QDs) have attracted significant research interest in the last few years. Because of their unique optical properties, such as tunable absorption and fluorescence emission spectra, high molar extinction coefficients, and high photoluminescence, QD-based materials are promising candidates for application in photodetectors, photovoltaics, LEDs, and optical sensing. Materials based on Hg- and Pb QDs are well studied so far, but their toxicity limits their application in many consumer products. III-V semiconductors are highly promising Pb- and Hg-free alternative materials.

The center of my research is the synthesis of InSb QDs, which are also part of the III-V semiconductor family.  More specifically, I am trying to introduce specific dopants into InSb QDs, in order to improve their optical properties.
