Upconversion luminescence in transparent oxyfluoride glass ceramics containing hexagonal NaErF4
(Elsevier, 2019)
Transparent oxyfluoride glass ceramics containing hexagonal NaErF4 nanocrystals were synthesized by a heat treatment of a precursor glass obtained by the melt quenching technique. Combined X-ray diffraction (XRD) and ...
Low-temperature studies of Cr3+ ions in natural and neutron-irradiated Mg-Al spinel
(American Institute of Physics, 2020)
Original results on the EPR and photoluminescence Cr3+ ions in natural magnesium aluminum spinel (MgAl2O4) are presented. The photoluminescence spectra of Cr3+ ions in natural MgAl2O4 have been measured before and after ...
