To overcome this limitation, we introduce a cluster\u2010level chirality strategy in a 0D framework by incorporating chiral metal halide clusters.

These enantiomers exhibit bright self\u2010trapped excitons emission at 625\u00a0nm with photoluminescence quantum yields above 40%, along with strong circularly polarized luminescence (\n                    <jats:italic>g<\/jats:italic>\n                    <jats:sub>lum<\/jats:sub>\n                    \u00a0\u2248\u00a0\u00b17\u00a0\u00d7\u00a010\n                    <jats:sup>\u22123<\/jats:sup>\n                    ), among the highest reported to date for chiral Antimony\u2010based hybrids.
