Nanocrystalline ZrO2 fine powders were prepared via the one-pot reaction followed by annealing from 700 to 1100 °C in air. It is believed that generation of excess oxygen vacancies within nanocrystalline primarily responsible for room-temperature tetragonal phase stabilization below a critical size, and transformation monoclinic happened process. Luminescent properties greatly affected transition Two bands centered at 350 470 nm observed ZrO2. The electrons trapped creating F centers...
Abstract The burgeoning phosphor‐converted near‐infrared light‐emitting diodes (pc‐NIR LEDs) have important applications in special illumination and spectroscopy analysis.

Natural systems give the route to design periodic arrangements with mesoscopic architecture using individual nanocrystals as building blocks forming colloidal crystals or supracrystals. The collective properties of such supracrystals are one main driving forces in materials research for 21st century potential applications electronics biomedical environments. Here we describe two simultaneous supracrystal growth processes from gold nanocrystal suspension, taking place solution and at...
Abstract Nanoparticle (NP) assemblies have been studied over the past several decades, and field is advancing more quickly reaching into diverse fields. Reports issued from academic industrial laboratories driven these advances. Countless breakthroughs reported in widely different fields, including thermoelectronics, photoelectronics, catalysts, energy sources, medical carriers. A “family tree” clearly needed to accurately trace developments study of NP assemblies. This review uses...
Abstract Far‐red phosphor‐converted light‐emitting diodes are receiving increasing attention as an essential component of the next‐generation plant‐growth lights. However, developing far‐red phosphors with high quantum efficiency, low thermal quenching, and suitable emitting wavelength is crucial urgent.

For self-assembled nanocrystals in three-dimensional (3D) superlattices, called supracrystals, the crystalline structure of metal (either single domain or polycrystalline) nanocrystallinity is likely to induce significant changes physical properties. Previous studies demonstrated that spontaneous segregation takes place colloidal solution upon self-assembling 5 nm dodecanethiol-passivated Au nanocrystals. This allows exclusive selection and polycrystalline nanoparticles consequently...
Supercrystalline nanocomposites (SCNCs) are inorganic-organic hybrid materials with a unique periodic nanostructure, and thus they have been gaining growing attention for their intriguing functional properties parallelisms hierarchical biomaterials. Their mechanical behavior remains, however, poorly understood, even though its understanding control important to allow SCNCs' implementation into devices. An aspect that has not tackled yet is time-dependent deformation behavior, which...

We use broadband picosecond acoustics to detect longitudinal acoustic phonons with few-gigahertz frequency in three-dimensional supracrystals (with face-centered cubic lattice) of 7 nm cobalt nanocrystal spheres. In full analogy atomic crystals, where propagate the speed sound through coherent movements atoms lattice out their equilibrium positions, these are replaced by (uncompressible) nanocrystals and bonds coating agents (carbon chains) that act like mechanical springs holding together...
