原始摘要(英文原文)· Original abstract
Enantiomeric protonated 2-amino-1-propanol (APH+) chiral cations are introduced to partially substitute K+ sites in K2TiF6:Mn4+, triggering effective chirality transfer to Mn4+ luminescent centers. The as-prepared chiral hybrid fluorides exhibit mirror-image circular dichroism and narrow-band red CPL originating from Mn4+ 2Eg → 4A2g transitions, with a maximum |glum| up to 2.0 × 10-3.
