Time: 9.00

Location: room E 005

Fluorescent and magneto-optical properties of cerium-doped yttrium aluminium garnet nanoparticles are studied by means of confocal microscopy under ambient conditions. It is shown that Ce:YAG nanoparticles exhibit very bright fluorescence which makes them perfect photostable fluorescent biomarkers. In addition, all-optical manupulation and detection of cerium electron spin is confirmed by measuring optically-induced magnetization and quantum beats. Photon correlation measurements show that creation of a single emitting cerium center is feasible, therefore, making it a good candidate for all-optically addressable spin qubit.
