Developing solid-state luminescent materials with bright long-wavelength emissions is of considerable practical importance in light-emitting diodes (LEDs) but remains a formidable challenge. Here, novel structure engineering strategy reported to realize fluorescence (FL)-emitted carbon dots (CDs) from visible near-infrared region. This the first report such an extended wavelength emission self-quenching-resistant CDs. Notably, quantum yields these CDs are remarkably improved up 67.7%, which...
Abstract Room temperature phosphorescence (RTP) has emerged as an interesting but rare phenomenon with multiple potential applications in anti‐counterfeiting, optoelectronic devices, and biosensing. Nevertheless, the pursuit of ultralong lifetimes RTP under visible light excitation presents a significant challenge. Here, new phosphorescent materials that can be excited by record‐long are demonstrated, realized through embedding nitrogen doped carbon dots (N‐CDs) into poly(vinyl alcohol)...
Abstract The development of bright and long‐lived aqueous room‐temperature phosphorescent (RTP) materials holds paramount importance in broadening the application scope RTP material system. However, conventional usually exhibit low efficiency short lifetime solution. Herein, an situ host–guest strategy is proposed to achieve cyanuric acid (CA)‐derived carbon nitrogen dots (CNDs) composite (CNDs@CA) that demonstrates a significant enhancement both quantum yield (QY) mediated by water....
Abstract Multicolor carbon dot (CD)‐based nanomaterials offer a variety of opportunities for potential applications in bioimaging, optoelectronic devices, and information security. However, it still remains challenge to modulate the conjugated π‐structure CDs achieve multicolor room‐temperature phosphorescence (RTP). Herein, authors present strategy based on thermally driven amorphous−crystalline phase transition carbonized polymer dots (CPDs) with emission color tunable from green...
N and P codoped carbonized polymer dots (NP-CPDs) exhibit a relatively long RTP decay time over 23 s among most carbon dot-based materials reported thus far. Such NP-CPDs are applied to illustrate applications in information security.
Carbon dots (CDs) that simultaneously exhibit full-color and wide-range lifetime-tunable room-temperature phosphorescence (RTP) are of particular interest for potential applications in encryption information security. However, achieving such CDs remains a great challenge thus far. This work reports on the development straightforward host–guest approach, where metal–organic framework (MOF) host acts as an RTP activator fluorescent CDs, with color dependent component. The developed CDs@MOF...
Four room-temperature phosphorescent carbonized polymer dots (CPDs) with wide-range tunable lifetimes from 730 ms to 2.26 s are prepared and applied for naked-eye visible multiplexing.
Luminescent carbon dots (CDs) have drawn much attention in terms of photoelectronic applications, most which are focused on single-component white-light emission. However, it still remains a significant challenge to create high-quality white-light-emitting CDs with tunable correlated color temperatures (CCTs). The theoretical calculation is initially used predict that the enlargement conjugated sp2 domain induces redshift fluorescence (FL) and room temperature phosphorescence (RTP) emissions...
This study explored a simple and fast method utilizing ultraviolet (UV) irradiation to synthesize CdTe/CdS/ZnS QDs in aqueous solution. Based on the reaction of photolysis chemical deposition, CdS ZnS shell can be successively deposited around thiol-capped CdTe cores through interaction Cd2+/Zn2+ S2− produced by UV irradiation. The effect time, ratios thioglycolic acid (TGA)/Cd TGA/Zn formation, stability, photoluminescence (PL) intensity QDs, was systematically investigated. Keeping ratio...
