The photoluminescence (PL) of cuprous iodide (CuI) has drawn significant attention in the scientific community. In order to investigate the growth methods and environmental conditions on the fluorescence, we first prepared CuI via immersion of copper in hydroiodic acid. This method is beneficial for the growth of large grains (> 20 μm) with intensive red fluorescence emission at 708 nm. The fluorescence has a high quantum yield (34 %), and superior stability. Then we studied the fluorescence behaviors in water. We observed fluorescence quenching, which is due to the energy transfer. Additionally, we studied the effect of temperature on the fluorescence. We found that the fluorescence intensity increased initially then decreased as the temperature increased. The underlying mechanism was analyzed in terms of fluorescence quencher (water) removal and thermal quenching. By controlling heating, we successfully obtained intensive and pure red fluorescence. Finally, we explored the potential application of the red fluorescent of CuI in optical communication. The results demonstrate bit error rates within permissible range of forward error correction, highlighting the superior performance of CuI in optical communication systems.

Carbon nanomaterials (CNMs) exhibit excellent performance and potential application value in optical, electric, magnetic and thermal owing to their unique low dimensional structures, high specific surface areas and excellent electrical conductivities, however, the random orientation of CNMs in polymer dispersions negatively affects their optimal performances. Herein, the orientation of CNMs induced by an electric field in dispersions was investigated. The arrangement of carbon black, carbon nanotubes and graphite nanoplatelets in solvents under an electric field was characterized using a stereoscopic microscope. The effects of solvent type, nanomaterial concentration and electric field conditions on the orientation of the CNMs were systematically investigated. The results showed that the CNMs generally exhibited good electric field‐induced orientations in solvents with a low relative dielectric constant. The orientation structure resulting from using an appropriate CNMs concentration was relatively uniform and continuous. In particular, a more regular orientation structure was achieved upon applying an electric field (100 V/mm; 1000 Hz) for 30 s. Interestingly, well‐oriented CNMs in a solvent can also orient in polymer dispersions that are soluble in such a solvent. This extension of the orientation of CNMs from solvents to polymer dispersion systems provides a novel idea for preparing high‐performance composites.
