TiO2 doped with europium (Eu): Synthesis, characterization and catalytic performance on pesticide degradation under solar irradiation

Photoluminescence modification of europium(iii)-doped MAl2O4 (M = Zn, Mg) spinels induced by Ag@SiO2 core–shell nanoparticles

“…They have been used in the field of electronics, 7,8 biotechnology and medicine, [9][10][11] and catalysis. 12,13 Eu 3+ has a characteristic red-emission due to the 5 D 0 → 7 F 2 transition, which is called hypersensitive transition because it is extremely sensitive to the local environment around the Eu 3+ ion. [14][15][16] For materials that have emission in the visible range of the electromagnetic spectrum, their photoluminescence (PL) can be improved by placing these luminophores in the vicinity of metallic nanoparticles (NPs) due to the plasmon resonance of NPs.…”

Effect of Doping TiO2 NPs with Lanthanides (La, Ce and Eu) on the Adsorption and Photodegradation of Cyanide—A Comparative Study

“…The FTIR spectrum of TiO 2 reveals the existence of a broad band in the region of 540–900 cm −1 , which is assigned to Ti–O and Ti–O–Ti stretching vibrations [ 55 , 56 ]. After doping, the main change was identified in this region, presenting new unresolved bands around the 500–600 cm −1 region that could be attributed to Ln–O stretching modes of vibrations.…”

Materials Design and Development of Photocatalytic NOx Removal Technology

“…The utilization of Eu 3+ with its large cation size (0.95 Å) for doping into the lattice structure of photocatalysts introduces strain or defects, potentially generating energetic states within band gap materials, which in turn can enhance photocatalytic activity through the mitigation of photo-charge recombination [54,55]. Pastor et al developed Eu 3+ -doped Zn 2 Al-LDHs, observing that an optimal level of Eu 3+ doping not only reduced photocharge recombination but also increased the production of radicals [56].…”
