The formation of nanoaggregates makes a great difference to the improvement of photodynamic therapy (PDT) performance to some extent, but constructing stable aggregates with a clear structure is simultaneously a big challenge for us. Herein, just by electrostatic interaction, cationic 2PAHs and anionic FBA351, regarded as acceptor (A) and donor (D), respectively, are utilized to prepare stable aggregate...
Rapidly evolving group‐10 transition metal dichalcogenides (TMDCs) offer remarkable electronic, optical, and mechanical properties, making them promising candidates for advanced optoelectronic applications. Compared to most TMDCs semiconductors, group‐10‐TMDCs possess unique structures, narrow bandgap, and influential physical properties that motivate the development of broadband photodetectors, specifically...
Ultra‐Narrow Linewidth Photo‐Emitters
In article number 2204302, Khurram Shehzad, Hui Wu, Zhiming Wang, and co‐workers report that hot‐pressing bulk Selenium into nanoflakes induces structural changes in the Selenium lattice, which leads to ultra‐narrow bandwidth photoemission with full width at half maximum of 330 ± 90 μeV, an order of magnitude narrower than the other 2D materials at 300 K.
Photoluminescence (PL) in state‐of‐the‐art 2D materials suffers from narrow spectral coverage, relatively broad linewidths, and poor room‐temperature (RT) functionality. The authors report ultra‐narrow linewidth photo‐emitters (ULPs) across the visible to near‐infrared wavelength at RT in polymorphic selenium nanoflakes (SeNFs), synthesized via a hot‐pressing strategy. Photo‐emitters in NIR exhibit...
In this work, a near‐ultraviolet (NUV) emitter, 2MCz‐CNMCz, with hot‐exciton property is designed based on a “long‐short axis” strategy, which exhibits good thermal stability, bipolar carrier transport ability, and high T1 energy level. Its nondoped NUV organic light‐emitting diode (OLED) achieves a record maximum external quantum efficiency (ηext) of 7.76%, with a peak at 404 nm and CIE coordinates...
Aggregation‐induced emission (AIE) fluorogens provide new opportunities to promote efficient reactive oxygen species (ROS) production in aggregates, which represent the promising candidates to construct theranostic nanoparticles for photodynamic therapy (PDT), but the size effect has been rarely explored. Herein, a universal method to fabricate organic nanoparticles with controllable sizes is reported...
The integration of highly luminescent CsPbBr3 quantum dots on nanowire waveguides has enormous potential applications in nanophotonics, optical sensing, and quantum communications. On the other hand, CsPb2Br5 nanowires have also attracted a lot of attention due to their unique water stability and controversial luminescent property. Here, the growth of CsPbBr3 nanocrystals on CsPb2Br5 nanowires is...
Among the foreseeable therapeutic approaches at the cellular level, nanoplatform‐driven photothermal therapy is a thriving tool for the selective eradication of malignant tissues with minimal side effects to healthy ones. Hence, chemically versatile, near‐infrared absorbing plasmonic nanoparticles are distinctly appealing and most sought after as efficient photothermal agents. In this work, a straightforward...
In article number 1803282, Patrizia Canton, Fiorenzo Vetrone, and co‐workers synthesize, via a green approach, water‐dispersible plasmonic copper sulfide nanoparticles as highly efficient light‐to‐heat transducers featuring a readily tailorable surface. Upon comparing the results from the experimental assessment and mathematical modelling of the nanoparticles' optical and photothermal properties,...
