2012年4月20日 · The X-ray diffraction pattern reveals that the phosphor crystallized in the hexagonal α-Al2O3 phase directly from the combustion reaction. The EPR spectrum exhibits an intense resonance signal with effective g value at g=3.33 along with a few weak resonance signals with effective g values at g=13.7, 2.34, 1.95, 1.49, and 1.26.

Through the impregnation method, Ag catalysts with different support (such as TiO2 and γ-Al2O3) were prepared and then tested for catalytic oxidation of formaldehyde (HCHO) at low temperatures....

2022年10月1日 · The Electron Paramagnetic Resonance (EPR) spectra of α-Al 2 O 3:Cr 3+ were measured with Bruker ELEXSYS-II E500 CW-EPR spectrometer at room temperature. The magnetic field modulation parameters were 100 kHz and 0.2 mT; the microwaves were generated at 9.835 GHz frequency and 2 mW power.

In concentrated α-Al2O3-Cr2O3 solid solutions, magnetic interactions lead to paramagnetic species being undetectable. To study their reliability as primary standards in the quantitative EPR spectroscopy, a large series of pure paramagnetic compounds with known spin concent
