1. Hybrid carbon nanosheets (CNSs) in different solvents of varying polarity.
2. Synthesis and optical properties of hybrid carbon nanosheets (CNSs).

A recent study, affiliated with UNIST has engineered a new type of carbon nanomaterials, capable of changing shapes and colors depending on the type of solvents used. Such materials have attracted much attention owing to their unique optical properties and structures. In the study, the joint research team, led by Professor Byung Soo kim and Professor Oh Hoon Kwon has presented a unique design and synthesis of hybrid carbon nanosheets (CNSs), which show a strong solvatochromic behavior with wide color tunability ranging from blue to orange and even to white in various solvents.

This unique hybrid CNS hosts clusters of carbon nanorings on the su...

These ionic materials exhibit optical properties not found in 2D covalent semiconductors eg graphene, making them promising alternatives to silicon for future electronic devices. To the growing list of 2D semiconductors, eg graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices, you can now add hybrid organic-inorganic perovskites...
