“…The nanostructure-based nanocomposites are single or polycrystals with nanoscale grain size. 115 The composition and size of nanostructures can vary depending on the type of nanostructure like extracellular vesicles, DNA nanostructures, and nanoneedles. Recently, the nanostructures have also been exploited to deliver CRISPR/Cas tools which will be discussed in this section.…”

“…Thus, the synthesis of IrO 2 in its nanostructured form (structures presenting at least one dimension on the nanoscale) has become an increasing field of interest in research. In particular, nanostructured materials that exhibit chemical, optical, mechanical and electrical properties modified with respect to the corresponding bulk material, due to size and quantum effects [81][82][83][84][85][86]. Several types of nanostructures, with different dimensionality, are known, including zero-dimensional (0D, quantum dots and nanopowder), one-dimensional (1D, nanotubes, nanowires and nanorods), and two-dimensional (2D, nanostructured films) nanomaterials [86].…”

Iridium Oxide (IrO2) is a metal oxide with a rutile crystalline structure, analogous to the TiO2 rutile polymorph. Unlike other oxides of transition metals, IrO2 shows a metallic type conductivity and displays a low surface work function. IrO2 is also characterized by a high chemical stability. These highly desirable properties make IrO2 a rightful candidate for specific applications. Furthermore, IrO2 can be synthesized in the form of a wide variety of nanostructures ranging from nanopowder, nanosheets, nanotubes, nanorods, nanowires, and nanoporous thin films. IrO2 nanostructuration, which allows its attractive intrinsic properties to be enhanced, can therefore be exploited according to the pursued application. Indeed, IrO2 nanostructures have shown utility in fields that span from electrocatalysis, electrochromic devices, sensors, fuel cell and supercapacitors. After a brief description of the IrO2 structure and properties, the present review will describe the main employed synthetic methodologies that are followed to prepare selectively the various types of nanostructures, highlighting in each case the advantages brought by the nanostructuration illustrating their performances and applications.

In this work, we investigated the synthesis temperature effect on the crystal growth of Eu-doped ceria nanostructures synthesized via the microwave-assisted hydrothermal method and how it influences their red-light emission. Sphere-like nanoparticles, nanorods, nanorods/nanocubes, and nanocubes were obtained by gradually increasing the synthesis temperature. The structural analysis revealed that the nanocubes displayed higher crystallinity and lower structural disorder in comparison to the other morphologies. X-ray photoelectron spectroscopy (XPS) spectroscopy showed that oxygen vacancies were the predominant defect. The intensity of the photoluminescence emissions of the nanocubes was 60 times higher than that of the sphere-like nanoparticles and nanorods, indicating that the structural symmetry in this morphology is suitable for doping with Eu3+, displaying greater photoluminescence efficiency. The nanocubes also displayed excellent red-light emission, with coordinates (0.63,0.37) close to the red RGB primary at (0.64, 0.32). The lifetime values increased with higher synthesis temperatures. This trend suggests a structural correlation of different morphologies, defects, and homogeneity of the Eu3+ distribution in the crystal lattice and the photoluminescence emission and quenching. Therefore, we showed that controlling the morphology of Eu-doped CeO2 nanostructures is a powerful tool to improve its photoluminescence properties, which is valuable for applications as a red phosphor.
