Improvement in the emission properties of a luminescent anionic dye intercalated between the lamellae of zinc hydroxide-layered

- Effective, easy and rapid intercalation of luminescent pyranine anionic dye into zinc hydroxide-layered (ZHL-layered).
- Disaggregation of the dye by the ZHL-layered material.
- Increase in the quantum yield photoluminescence of the dye occluded between the lamellae of the inorganic host.
- Luminescent organic-inorganic hybrids with green emission.
