Special Issue Information

Dear Colleagues,

Rare-earth elements are valuable strategic resources known for their unique physical and chemical properties. Nanostructured rare-earth materials, with their exceptional size, structure, and properties, exhibit remarkable functionalities that surpass conventional materials. In addition, these nanomaterials possess distinct optical, electrical, thermal, and magnetic properties that create novel characteristics. In particular, they exhibit excellent properties in energy conversion, nanomagnetism, catalysis, luminescence, and hydrogen storage.

In this Special Issue, we will delve into the latest research findings, development trends, and practical applications of rare-earth functional materials, aiming to gain further understanding of their unique value. We welcome contributions devoted to nanostructured rare-earth materials. Research areas may include (but are not limited to) the following:

  1. Design and preparation of rare earth-based, electromagnetic wave-absorbing nanomaterials;
  2. High-performance rare earth-based magnetic materials;
  3. Rare earth-based hydrogen storage materials and their applications;
  4. Precision processing of rare earth precursors and polishing materials;
  5. Rare-earth luminescent materials and photoelectric devices;
  6. New testing and characterization methods in rare-earth nanomaterials;
  7. Review articles on the progress of rare earth-based, electromagnetic wave-absorbing nanomaterials.

We report a joint high-pressure experimental and theoretical study of the structural, vibrational, and photoluminescent properties of pure and Eu3+-doped cubic Y2O3 nanoparticles with two very different average particle sizes. We compare the results of synchrotron X-ray diffraction, Raman scattering, and photoluminescence measurements in nanoparticles with ab initio density-functional simulations in bulk material with the aim to understand the influence of the average particle size on the properties of pure and doped Y2O3 nanoparticles under compression. We observe that the high-pressure phase behavior of Y2O3 nanoparticles depends on the average particle size, but in a different way to that previously reported. Nanoparticles with an average particle size of ~37 nm show the same pressure-induced phase transition sequence on upstroke and downstroke as the bulk sample; however, nanoparticles with an average particle size of ~6 nm undergo an irreversible pressure-induced amorphization above 16 GPa that is completed above 24 GPa. On downstroke, 6 nm nanoparticles likely consist of an amorphous phase. Full article
