Abstract High concentrations of defects are introduced into nanoscale ZnO through non‐equilibrium processes and resultant blue emissions comprehensively analyzed, focusing on defect origins broad controls. Some nanoparticles exhibit very strong emissions, the intensity which first increase then decrease with annealing. These visible interesting excitation dependences: 1) optimal energy for is near bandgap energy, but effective can obviously be lower, even 420 nm (2.95 eV < E g = 3.26 eV);...
Abstract Highly conductive polymer nanocomposites are greatly desired for electromagnetic interference (EMI) shielding applications. Although transition metal carbide/carbonitride (MXene) has shown its huge potential producing highly films and bulk materials, it still remains a great challenge to fabricate extremely with outstanding EMI performance at minimal amounts of MXenes.

A facile approach for the fabrication of novel black plasmonic colloidosomes assembled from Au nanospheres is developed by an emulsion-templating strategy. This self-assembly process based on a new reverse water-in-1-butanol emulsion system, in which water droplets can dissolve into 1-butanol (oil) phase at appropriate rate. These possess hexagonal close-packed multilayer shells and show low reflectivity intense broadband absorption owing to strong interparticle coupling, further...
