Efficient circularly polarized luminescence from zero-dimensional terbium- and europium-based hybrid metal halides
Zero-dimensional (0D) chiral hybrid metal halides (HMHs) with narrow-band circularly polarized luminescence (CPL) show considerable promise in three-dimensional displays. In this work, 0D (<i>S</i>/<i>R</i>-3MOR)<sub>3</sub>TbCl<sub>6</sub> and (<i>S</i>/<i>R</i>-3MOR)<sub>3</sub>EuCl<sub>6</sub> (abbreviated as <i>S</i>/<i>R</i>-TbCl, <i>S</i>/<i>R</i>-EuCl) enantiomers with characteristic rare-earth ion emissions are synthesized. <i>S</i>/<i>R</i>-TbCl and <i>S</i>/<i>R</i>-EuCl exhibit narrow-band green and red emissions with high photoluminescence quantum yields of (85-91)% and (48-52)%, respectively. These materials present distinct CPL signals with dissymmetry factors up to ±0.006 and ±0.009 for <i>S</i>/<i>R</i>-TbCl and <i>S</i>/<i>R</i>-EuCl, respectively. These chiroptical properties confer the potential for their applications in circularly polarized light-emitting diodes for future displays.
