Quantifying Mg-All cation distribution in MgAl2O4-spinel using Raman spectroscopy: An experimental calibration

Yunlu Ma et al.

Summary: This study presents a calibrated method for quantifying the Mg-Al cation distribution in MgAl2O4-spinel using Raman spectroscopy. The correlation between the inversion parameter x and the relative Raman intensities of specific peaks has been established by combining single-crystal X-ray diffraction and Raman data. This calibration enables convenient determination of the cation distribution in MgAl2O4-spinel of different geological origins.

Enhancement of X-ray-Excited Red Luminescence of Chromium-Doped Zinc Gallate via Ultrasmall Silicon Carbide Nanocrystals

David Beke et al.

Summary: A method of sensitizing zinc gallate nanoparticles with silicon carbide quantum dots is reported, enhancing near-infrared emission under X-ray and UV-vis light excitation. The formation of a ZnGa2O4 shell around the SiC nanoparticles and the band alignment for channeling excited electrons to chromium ions contribute to a significant increase in emission efficiency.

Probing the defects and trap distribution in MgAl2O4 nanocrystals through electron spin resonance and thermoluminescence

Savita et al.

Summary: Trap distribution in MgAl2O4 nanocrystals was investigated by analyzing thermoluminescence glow curves upon UV-irradiation. Different fuels were used in the synthesis process, resulting in varying trap concentrations and distributions at different annealing temperatures. Various trapping parameters were revealed through computerized glow curve deconvolution.
