Scientific Achievement
Nanorod composites with remarkably stable photonic properties are assembled from CsPbX3 perovskite nanocrystals (PNCs) and polymer-grafted graphene oxide (g-GO).
Significance and Impact
The work presents a unique self-assembly strategy to produce robust perovskite emissive materials, which may be generalized to other nanomaterials and greatly extend their potential applications.
Research Details
- PNC/g-GO composites assemble into uniform nanorod suprastructures.
- Resulting material is stable for months with little loss in photoluminescent quantum yield in films and solution.
- Emission color can be tuned across the visible spectrum by substituting the halide atom.
