Tuning optical properties of printable carbon quantum dots using near-field environment

Reversible Light-Responsive Solventless-Liquid Switch: Polarization-Induced Dynamic Surface Ordering–Disordering in Liquid-Like Carbon Quantum Dots

“…In this material, the properties of CQDs remain intact and the interaction between the polymer (canopy) and CQD (core) is well established. The electrostatic interaction helps the flexibility of the material as detailed in our recent findings . Our group has been working to develop smart nanomaterials with interesting plasmonic and electronic properties.…”

“…Our group recently reported CQD embedded poly(vinyl alcohol) photoconductive films. 8 The films showed increased electronic conductivity upon exposure to solar simulator due to near-field effect from closely packed CQDs in the composite film. Such phenomenon of photoconductivity by CQDs was the first report of its kind though the increments in observed current levels were pretty low (∼1−2 nA).…”

“…These materials possess interesting emission and redox properties . We have recently reported the synthesis of polymer-passivated CQDs and their surface modification into nanoionic materials (NIMs). , NIMs are interesting hybrid materials that show the combined effect of the core–corona–canopy structure . Introduced by Giannelis and co-workers, these materials possess huge potential for next generation functional materials that can be used as building blocks for future smart devices. − Most reported NIMs are room temperature solventless fluids that are stable in a wide temperature range.…”

“…The electrostatic interaction helps the flexibility of the material as detailed in our recent findings. 8 Our group has been working to develop smart nanomaterials with interesting plasmonic and electronic properties. We have reported that perturbations in the form of shear can produce dynamic changes in optical properties in gold-nanorod-based nanoionic materials (NIMs).…”
