“…Ce and Eu species are very popular as activators in different solid host lattices (single crystals, polycrystalline and glassy powders, ceramics) for producing multifunctional materials: as scintillators for neutron registration and X‐ray intensifying screens for medical purposes, as photosensitive materials for biomedical diagnostics, luminescence lamps, light‐emitting diodes, cathode ray tubes, etc. Previously we have reported on Ce, Cu, Eu, Mn and Ag species in tetraborate single crystals and silica .…”

Quartz glass doped with cerium (0.02–0.36 wt%) and europium (0.01–0.04 wt%) nanoparticles were prepared by a modified sol‐gel method. Ultraviolet‐visible optical absorption and steady‐state photoluminescence excitation‐emission techniques were applied for spectral characterization of samples. Absorption spectra for Ce/SiO2 samples showed two intense and broad bands of charge‐transfer (CT) character at 240 and 300 nm that were attributed to the O2– → Ce3+ and O2– → Ce4+ transitions, respectively. For Eu/SiO2 and CeEu/SiO2 samples, CT bands O2– → Eu3+ at 225 nm and non‐resolved ones O2– → Ce3+ at 245 nm were registered, respectively. Photoluminescence spectra of Ce/SiO2 samples showed the presence of Ce3+ ions emitting in the range of 413–438 nm caused by the 5d–4f transition. Photoluminescence spectra of Eu/SiO2 and CeEu/SiO2 samples featured the characteristic orange‐red emission arising from 5D0 → 7Fn manifolds (570–750 nm) of Eu3+ ions. The electric‐dipole 5D0 → 7F2 transition at 615 nm dominated in the Eu/SiO2 samples while the magnetic‐dipole transition 5D0 → 7F1 at 591 nm dominated in the CeEu/SiO2 double‐doped samples.

“…Recently, a microwave irradiation method has received considerable attention as a new promising method for the preparation of nanomaterials with controlled shape and size [18]. For instance, the microwave assisted precipitation method was successfully used in the preparation of monodispersed spherical Y 2 O 3 and Y 2 O 3 /Eu 3 þ nanocrystalline particles with size of 100-350 nm [19], and graphene modified LiFePO 4 /C nanocomposite [20].…”

“…Solid materials prepared by microwave calcination can obtain products that differ from those generated by conventional heating. Examples of this method include ceramic materials with improved microstructure, layered hydrotalcite-type oxide with strong basicity and nano-powders with low reaction temperature [30][31][32].…”
