Here, we obtained crystals of the organic-monolayer protected titanium-alloyed lanthanide nanoclusters (i.e., Eu₈Ti 10 NCs), where the TDMs of Eu³⁺ ions generate typically orthogonal polarization behaviors (i.e., π/σ-light) from the 5 D₀→ 7 F 1,2 transition. Most importantly, the Eu₈Ti₁₀ single crystal presents a remarkable polarized propagation with unprecedented anisotropy relevant to the crystallographic axis, thus resulting in an on-crystal optical modulator.
