Tunable Emission from Binary Organic One‐Dimensional Nanomaterials: An Alternative Approach to White‐Light Emission

Uniformly doped crystalline organic nanorods and nanowires are prepared by adsorbent-assisted physical vapor deposition. The emission color of the binary 1D nanomaterials can be controlled – and made to approach white light (see figure) – by changing the doping content, which is ascribed to intermolecular fluorescence resonance energy transfer between the two nanocrystalline components.
