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.
