Crystalline low-dimensional materials made of covalently bonded carbon atoms possess a diverse range of unique properties that are promising for various applications. Their properties can greatly vary, depending on their atomic arrangements, sizes, and dimensionality. In particular, the optical, mechanical, and thermal properties of carbon nanotubes and graphene have attracted considerable attention from both fundamental and applied viewpoints. From a physics point of view, carbon nanotubes and graphene, respectively, provide one- and two-dimensional platforms with characteristic spatial scales of only 1 nm for fundamental studies of quantum phenomena. Recent years have seen remarkable advances and innovations in the preparation of different types of large-scale architectures and devices of ordered and purified carbon nanomaterials. These developments are currently revolutionizing the field of optical science of carbon nanotubes and graphene toward real-world applications of carbon-based optoelectronic devices. In this article, we provide an overview on the frontier of this rapidly progressing research field.
