Innovative phosphorus and nitrogen dual-doped hollow carbon dots (PNHCDs) have been fabricated for anticancer drug delivery biological imaging. The functional groups of PNHCDs are introduced by simply mixing glucose, 1,2-ethylenediamine, concentrated phosphoric acid. This is an automatic method without external heat treatment to rapidly produce large quantities PNHCDs, which avoid high temperature, complicated operations, long reaction times. as-prepared possess small particle size,...
Owing to their diverse properties, fluorescent carbon dots (CDs) have attracted more attention and present enormous potential in development of sensors, bioimaging, drug delivery, microfluidics, photodynamic therapy, light emitting diode, so forth. Herein, a multifunctional sensing platform based on bright yellow CDs (Y-CDs) was designed for the label-free detection fluoroquinolones (FQs) histidine (His). The Y-CDs with superior optical biological merits including high chemical stability,...
The construction of ratiometric fluorescence assay has displayed fantastic advantages in improving semi-quantitative visualization capability by presenting successive color changes. Herein, long-wavelength emission nitrogen-doped carbon dots (N-CDs) were developed for intrinsic detection silver ions (Ag+) and glutathione (GSH), accompanied variation orange green. label-free N-CDs favorably obtained through one-step hydrothermal synthesis single at 618 nm under the excitation wavelength 478...
Activating room-temperature phosphorescence (RTP) emission in aqueous environments is a challenging feat because of the releasing nonradiative decay pathways. Here, design strategy was presented that effectively promotes presence RTP carbon dots (CDs) solutions by utilizing CDs and melamine to construct hydrogen-bonded networks form polymer (M-CDs). The obtained M-CDs not only enjoy an ultralong lifetime 664 ms, but also relatively high quantum yield 25% environment at 468 nm excitation....

Abstract Visible light is ubiquitous and safer than ultraviolet light; however, synthesizing ultralong‐lifetime room temperature phosphorescent (URTP) carbon dots (CDs) with visible‐light excitation remains a formidable challenge. Herein, an easy fast method for visible‐light‐excited URTP CDs devised. The synthesized have lifetime of 1.51 s which relatively long life RTP ever reported. Furthermore, it revealed that the dense core CDs, formation long‐chain polymers on surface, presence...
A schematic illustration for assaying Cr(<sc>vi</sc>) and Cys activity by CDs with both fluorescent colorimetric readouts.
Novel orange-emitting N-doped carbon dots (N-CDs) were prepared as fluorescent and colorimetric dual-mode probes for sensing nitrite (NO2-). The obtained N-CDs possessed fantastic optical properties specific responses to NO2-. NO2- could induce the fluorescence static quenching of N-CDs, a linear relationship was in range from 2 60 μM with detection limit 0.35 μM. More interestingly, exhibited ratiometric absorption signals visible color conversion (red-purple), which allowed development...
Efficient room-temperature phosphorescence (RTP) of carbon dots (CDs) usually is seriously limited to appropriate solid matrix or introduced heavy atoms responsible for promoting intersystem crossing and suppress vibrational dissipation between singlet triplet states. So, facile preparation efficient RTP CDs with nonmatrix still a highly difficulty challenging task. Here, we first reported subtle strategy induce free-matrix nitrogen-doped (NCDs). The NCDs are composed core hydrophilic...
The novel strategy for color-tunable carbon dots (CDs) with superior dispersibility in an aqueous solution is originally proposed a one-pot hydrothermal method. optimized emission of resulted CDs progressively shifts from green to red the adjustment precursor alkali acid. three representative entire green, yellow, and fluorescences prepared separately on alkaline, neutral, acidic solutions possess similar graphite structures their cores, while diversification PL emissions these are convinced...

Herein, an easy and effective ratiometric fluorescent nanoprobe for the selective detection of Pb2+ pyrophosphate (PPi) was developed based on label-free carbon dots (CDs). The CDs showed dual emission bands at 477 651 nm under a single-wavelength excitation (391 nm). PPi were sequentially detected by sensor with high reliability accuracy via exploitation fluorescence intensity ratio (F477/F651). exhibited selectivity excellent sensitivity than other analytes limits as low 0.055 μM 0.089 μM,...
