Highly amino-functionalized fluorescent carbon nanoparticles (CNPs) were fabricated by hydrothermal carbonization of chitosan at a mild temperature. They applied to bioimaging human lung adenocarcinoma A549 cells, showing low cytotoxicity and excellent biocompatibility.
Self-quenching in the aggregation state is overcome, and tunable solid-state photoluminescence of carbon-dot powder achieved. Furthermore, based on controllable optical property organic solvents, a novel concept, i.e., constructing dual-fluorescence morphologies from single luminescent species, presented to realize white-light emission.
Abstract Room temperature phosphorescence materials have inspired extensive attention owing to their great potential in optical applications. However, it is hard achieve a room material with simultaneous long lifetime and high quantum efficiency. Herein, multi-confined carbon dots were designed fabricated, enabling ultralong lifetime, efficiency, excellent stability. The multi-confinement by highly rigid network, stable covalent bonding, 3D spatial restriction efficiently rigidified the...
As one of the most promising fluorescent nanomaterials, fluorescence carbon dots (CDs) in solution is extensively studied. Nevertheless, synthesis multicolor solid-state (SSF) CDs rarely reported. Herein, with aggregation-induced emission are prepared using amine molecules, all them exhibiting dual at 480 nm (Em-1) and 580-620 (Em-2), which related to SS bonds dithiosalicylic acid conjugated structure attached CO/CN bonds, respectively. a strong electron-withdrawing group, increase CN...
Stable solid-state red fluorescence from organosilane-functionalized carbon dots (CDs) with sizes around 3 nm is reported for the first time. Meanwhile, a novel method also efficient construction of dual-fluorescence morphologies.
