Tuning the visible circularly polarized luminescence in highly emissive chiral terbium and europium chlorides

-Eu. In addition, the Tb-Eu alloyed compounds show excitation-dependent tunable CPL in the visible region with green, yellow, or red emission, which can be applied in anti-counterfeiting and information encryption. The highly tunable CPL emission and diversification of chiral RE metal halides in this work offer new routes for chiroptical optoelectronics.
