General description

Ytterbium(III) oxide (Yb₂O₃) is a wide bandgap(~3.26eV) material with high thermal stability, suitable for optoelectronic devices. It can be a potential host material for development of phosphors and solid-state lighting technologies. Furthermore, Yb₂O₃ nanofibers are being explored for renewable energy applications, particularly in enhancing the efficiency of solar cells and photocatalytic processes.

Application

  • Ytterbium (III) oxide reinforced novel TeO2–B2O3–V2O5 glass system: Investigation of the optical, structural, physical, and thermal properties of ytterbium oxide reinforced glass, highlighting improvements in material performance (Kilic et al., 2021).
  • Sonochemical preparation of a ytterbium oxide/reduced graphene oxide nanocomposite for supercapacitors with enhanced capacitive performance: Discusses the synthesis and application of ytterbium oxide/graphene nanocomposites in energy storage devices (Naderi et al., 2016).

Semiconductor quantum dot (QD)-sensitized lanthanide ions hold great promise in producing a broadly absorbing and sharply emitting luminophore, but their synthesis has proven to be difficult. We report the first synthesis of core/shell/shell InP/Ln xY1- xF3/ShF3 (Ln = Yb, Nd;

Photodynamic therapy (PDT) is a well-established modality for cancer therapy, which locally kills cancer cells when light irradiates a photosensitizer. However, conventional PDT is often limited by the extremely short lifespan and severely limited diffusion distance of reactive oxygen species
