Rare-earth doped nanocrystals possess optical transitions with significant either electric or magnetic dipole characters. They are of considerable interest for understanding and engineering light-matter interactions at the nanoscale with numerous applications in nanophotonics. Here, we study the ${}^{5}{D}_{0}{\ensuremath{\rightarrow}}^{7}{F}_{1}$ transition dipole vector in individual ${\mathrm{NaYF}}_{4}:{\mathrm{Eu}}^{3+}$ nanorod crystals by Fourier and confocal microscopies. A single…
