Biomolecules and nanostructures
The Optical Sciences group studies the interaction of light and matter at the nanoscale.
We do this by exploring ways to shape light and its environment. It's what we call
active and passive control. Our current focus is on the interaction of light with
biomolecules and nanostructures. We are part of Twente

The electronic structure of the lowest excited triplet state of the vanadate ion is investigated by determining the polarization of the emission from the individual spin sublevels with optically detected magnetic resonance techniques in zero field at 1.3 K. In addition, the polarization of the total emission is determined as a function of temperature between 7 and 530 K. An interpretation of the results based on an analysis of spin-orbit coupling points towards a localized excitation in which an electron is excited from a 2p-pi orbital of one of the oxygen ligands to a molecular orbital with a major contribution from the vanadium 3d(xy) orbital.
