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.
Hybrid carbon nanosheets (CNSs) in different solvents of varying polarity.
This unique hybrid CNS hosts clusters of carbon nanorings on the surface of graphene-oxide (GO) nanosheets as the product of the hydrothermal reaction of small molecular precursors in the presence of GO nanosheets. Moreover, under UV and visible-light excitation, the hybrid CNS exhibits tunable emission spanning the wide range of colors in a series of solvents with different polarities.
