Application

  • The role of Cerium, Europium and Erbium doped TiO2 photocatalysts in water treatment: A mini-review: This review explores the application of Erbium-doped TiO2 in water treatment for removing contaminants (Cerrato et al., 2022).
  • Quantum storage of entangled telecom-wavelength photons in an erbium-doped optical fibre: The study demonstrates quantum storage capabilities using erbium-doped optical fibers for telecommunications (Saglamyurek et al., 2015).
  • Twenty-three–millisecond electron spin coherence of erbium ions in a natural-abundance crystal: This paper discusses the long electron spin coherence times of erbium ions in crystals, relevant for quantum computing applications (Le Dantec et al., 2021).

Based on the open-aperture Z-scan measurement, we firstly uncovered the saturable absorption property of the topological insulator (TI): Bi2Se3. A high absolute modulation depth up to 98% and a saturation intensity of 0.49 GWcm(-2) were identified. By incorporating this novel

Charge and spin density waves, periodic modulations of the electron, and magnetization densities, respectively, are among the most abundant and nontrivial low-temperature ordered phases in condensed matter. The ordering direction is widely believed to result from the Fermi surface topology.

The ultraweak chemiluminescence (CL) from the reaction of hydrogen peroxide and carbonate is strongly enhanced by the branched NaYF(4):Yb(3+)/Er(3+) nanoparticle (NP) in the presence of aqueous ammonia. It was explained that ammonia catalyzes the decomposition of peroxymonocarbonate, which is the
