EPR response of yttria micro rods activated by europium

Defect Engineering for Quantum Grade Rare-Earth Nanocrystals

“…Two resonance lines at 335.1 mT (line I) and 341.3 mT (line II) can be observed in both cases, corresponding to g = 2.004 and g = 1.967, respectively. Similar EPR signals have been previously observed in Y 2 O 3 . ,− Accordingly, the lines in Figure were attributed to interstitial superoxide anions (line I) and charged oxygen vacancies (line II), i . e ., an oxygen vacancy center with a trapped electron.…”

Mining and Metallurgical Complex in Industrial and Postindustrial Development of Society

“…All high-tech, high technologies in one way or another use the components consisting of the high-tech metals and alloys, made from various combinations of many traditional metals and rare, rare-earth elements. Materials with rare earth elements have excellent properties, the importance of which is recognized throughout the world [8][9][10][11][12][13][14]. All innovative solutions in the field of space and rocket engineering, nuclear and hydrogen energy, nanotechnologies, medicine, biotechnologies, communications, etc.…”

“…In the world of innovative and high technologies, the following expensive REMs are widely used: indium, scandium, platinum, rhenium, palladium, osmium, lutetium, zirconium, selenium, tellurium, cobalt, cadmium, etc. [10][11][12][13][14][15].…”

Synthesis of Thulium-yttria Nanoparticles with EPR Response

“…Oliveira et al [17] obtained multi-colour-emitting, highcrystalline and micro-sized Y2O3:Eu 3+ ,Er 3+ ,Yb 3+ particles using sorbitol as an alternative to enhance the luminescence of Pechini-derived phosphors. In our recent study [18], it was found out that the dosimetric characteristics of yttria were improved by using 2at.%Eu as dopant. A linear EPR doseresponse behaviour was recorded in a range of dose from 0.001 to 50kGy.…”
