Carbon Nanolights in Piezopolymers are Self‐Organizing Toward Color Tunable Luminous Hybrids for Kinetic Energy Harvesting

“…Carbon quantum dots (CQDs), an emerging star of carbon nanomaterials, are attracting considerable attention in the field of optoelectronics and energy storage/conversion, owing mainly to their unique physiochemical, optical, and electronic properties . CQDs combine favorable attributes of tunable photoluminescence (PL), resistance to photobleaching and simple synthetic routes without incurring the burden of elemental scarcity . Their advantages have introduced them as a nontoxic and environmentally friendly alternative to traditional heavy‐metal–based quantum dots (QDs) .…”

“…CQDs combine favorable attributes of tunable photoluminescence (PL), resistance to photobleaching and simple synthetic routes without incurring the burden of elemental scarcity . Their advantages have introduced them as a nontoxic and environmentally friendly alternative to traditional heavy‐metal–based quantum dots (QDs) . CQDs are quasispherical nanoparticles, with ultrafine sizes below 10 nm, and they can be amorphous or nanocrystalline with sp 2 carbon clusters .…”

CQDs are quasispherical nanoparticles, with ultrafine sizes below 10 nm, and they can be amorphous or nanocrystalline with sp 2 carbon clusters . PL emission is the predominant property of CQDs, and they present excitation wavelength‐independent and excitation wavelength‐dependent fluorescence with different PL colors.…”

“…PL emission is the predominant property of CQDs, and they present excitation wavelength‐independent and excitation wavelength‐dependent fluorescence with different PL colors. Being asserted as the next big small things, these emergent carbon nanolights hold great promise to serve as inorganic building blocks for future optoelectronic nanohybrids and nanodevices, though the research is still at the early stage …”

“…Kinetic mechanical energy is prevalent everywhere we live, which exists in various forms, such as human movement, object vibration, water flow, wind whispering, and so forth. Consequently, effective conversion of mechanical energy into electricity is of critical importance for the sustainable operation of self‐powered electronic devices and systems . Diversified approaches have been developed via the mechanisms of electromagnetic induction, electrostatic generation, or piezoelectric effect .…”
