Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams
Advanced Optical Materials, EarlyView.Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.
