Ultralong room temperature phosphorescent (RTP) materials have a wide range of applications in information encryption, bio-imaging, optoelectronics, and display illumination. Among them, blue-emitting RTP with high quantum yield (QY) ultralong luminescence been challenge the field materials. Herein, we prepared blue-to-violet carbon dot (CD) composites color stability by mixing boric acid pyromellitic acid, trimesic terephthalic separately, pyrolyzing them at identical conditions, leading to...

Abstract Long‐lived room temperature phosphorescence (RTP) materials have many potential applications in areas such as luminescent lighting, biological imaging, and information security owing to their unique optical properties. However, traditional RTP are challenged by the fact that can be easily quenched dissolved oxygen solvent‐assisted relaxation, making it difficult for them emit aqueous solutions, particularly extreme pH environments. In this study, a multicolor carbon dot‐based...

Carbon dots (CDs) were hydrothermally synthesized using citric acid as carbon source and ethylenediamine additive. The as-obtained CDs then subjected to ultraviolet (UV) irradiation, resulting in ultraviolet-irradiated (UVCDs). morphology size of characterized by transmission electron microscopy. Elemental analysis (EA) was employed explore the composition CDs. surface functional groups investigated with help Fourier transformation infrared spectroscopy. Fluorescence spectrometry...

With the explosive development of research on phosphorescent carbon dots (CDs), it is great significance to explore their mechanisms and establish relationship among mechanism–structure–property. However, owing diversity dot structure, there still no definite unified model describe them. In this review, emission mechanism (including promotion ISC process stabilization triplet exciton) factors affecting property CDs core state, surface synergistic effect above-mentioned, environmental...

The controlled generation of reactive oxygen species (ROS) to selectively epoxidize styrene is a grand challenge. Herein, cyano-group-modified carbon nitrides (CNCYx and CN-Ty) are prepared, the catalysts show better performance in regulating ROS producing oxide than cyano-free sample. situ diffuse reflectance infrared density functional theory calculation results reveal that cyano group acts as adsorption activation site oxygen. X-ray photoelectron spectroscopy NMR spectrum confirm bonds...

In order to explore a stable and biocompatible material for encapsulating magnetic nanoparticles supporting thermosensitive polymers, the present study describes facile route preparing monodisperse hybrid microspheres with superparamagnetic cores, in which Fe3O4 nanocrystals are encapsulated carbon microsphere matrices (Fe3O4/carbon). Magnetic core/shell structure were prepared using Fe3O4/carbon as N-isopropylacrylamide monomer, potassium persulfate initiator N,N-methylene bisacrylamide...
