Chiral copper nanoclusters with enhanced circularly polarized luminescence and room-temperature phosphorescence.

This work explores the frontier of chirality in copper nanoclusters (CuNCs), which exhibit strong room-temperature phosphorescence along with enhanced circularly polarized luminescence (CPL) at low temperature. CuNCs display promising chiroptical activity, owing to the chirality transfer from surface ligands, thereby positioning CuNCs as emerging candidates for next-generation photonic applications.
