Abstract

Abstract : Excellent ceramic materials emit colorful circularly polarized luminescence (CPL) in spite of their high‐temperature syntheses of up to 1000 °C. The process consists of three very simple self‐controlled steps: 1) self‐generation of a nanofibrous polymeric complex polyethylenemine/tartrate (PEI/tart) in water; 2) self‐deposition of silica around the complex to form chiral SiO2 @PEI/tart hybrids; 3) self‐encapsulation of lanthanide ions into the hybrid to form a precursor of SiO2 @PEI/tart/Ln 3+ . Final sintering of the precursors affords the circularly polarized light (CPL)‐active ceramics with chiral silica hosts and emissive lanthanide guests.
