Understanding light harvesting and charge separation in molecular systems

Our research

We use theoretical approaches such as Time Dependent Density Functional Theory, structural characterization by Nuclear Magnetic Resonance Spectroscopy, and optical spectroscopy to understand the journey of photo-induced charges in organic and hybrid materials.

We have two main projects ongoing:

i. Design, synthesis and characterization of molecular systems for light harvesting and charge separation, funded by FAPESP;

ii. Design of upconversion and persistent luminescence nanocomposites: from fundamentals to applications in energy conversion and storage, funded by CNPq;

We have fellowships available for Undergrad, Master and PhD students. You can take part in the Physics Program or the Nanomaterials and Advanced Materials Program.

Our PhD and Master projects are delineated in the Projects
