Special Issue Information

Dear Colleagues,

Rare-Earth (RE) doped materials are relevant components of physical, chemical, and biomedical systems. They are currently exploited in a number of devices including solid-state lasers, phosphors, displays, telecom systems, sensors and quantum memories. In addition, the manipulation of their optical properties at the nanoscale provides opportunities to further enlarge their multifunctionality in many different strategic areas. Some examples include bio-imaging, medical diagnosis and therapy, green technologies for solid-state lighting, photovoltaics and energy conversion in solar cells, sensing, quantum information and plasmon-assisted nanophotonics.

This Special Issue of Nanomaterials aims to highlight the unique properties and countless applications of “Rare Earth Doped Materials at the Nanoscale” by collecting a compilation of articles in the form of research papers or reviews reflecting the most recent progress on this dynamic and active research field. Topics include, but are not limited, to:

  1. Optical properties of rare-earth doped materials at the nanoscale
  2. Nanostructured functional materials and novel nanofabrication technologies for rare-earth based photonic devices
  3. Rare-earth doped nanomaterials for biomedical, sensing, photonics, optoelectronics, solar cells, quantum information
  4. Modelling and advanced characterization methods of rare-earth doped systems at the nanoscale
  5. Other studies involving rare earth emitters in nanoscience and nanotechnology

Transparent oxyfluoride glass-ceramic films and self-supported layers with composition 80SiO2-20LaF3 doped with Er3+ have been successfully synthesized by sol-gel process for the first time. Crack-free films and self-supported layer with a maximum thickness up to 1.4 µm were obtained after heat treatment at the low temperature of 550 °C for 1 min, resulting in a LaF3 crystal fraction of 18 wt%, as confirmed by quantitative Rietveld refinement. This is the highest value reported up to now for transparent oxyfluoride glass-ceramics prepared by sol-gel. This work provides a new synthesis strategy and opens the way to a wide range of potential applications of oxyfluoride glass-ceramics. The characterization by a wide range of techniques revealed the homogeneous precipitation of LaF3 nanocrystals into the glass matrix. X-ray absorption spectroscopy and electron paramagnetic resonance confirmed that the Er3+ ions are preferentially embedded in the low phonon-energy LaF3 nanocrystals. Moreover, photoluminescence (PL) measurements confirmed the incorporation of dopants in the LaF3 nanocrystals. The effective concentration of rare-earth ions in the LaF3 nanocrystals is also estimated by X-ray absorption spectroscopy. Full article
