A First Wide‐Open LDH Structure Hosting InP/ZnS QDs: A New Route Toward Efficient and Photostable Red‐Emitting Phosphor

The architecture of Zn-Al layered double hydroxides (LDHs), organo-modified with bola-amphiphiles molecules, is matching its interlayer space to the size narrow-band red-emitting InP/ZnS core–shell quantum dots (QDs) form original high-performance functional organic–inorganic QD-bola-LDH hybrids. success size-matching (SMIS) approach confirmed by X-ray diffraction, small angle scattering (SAXS), TEM, STEM-HAADF, and photoluminescence investigations. QD-Bola-LDH hybrid exhibits a yield three times higher than that pristine QDs provides an easy dispersion into silicone-based resins, what makes SMIS change paradigm compared intercalation chemistry using common host structures. Moreover, this novel presents low QD–QD energy transfer comparable obtained for in suspension. Composite silicone films incorporating (0.27 wt%) hybrids further show remarkable improved photostability relative QDs.
