Upconversion luminescence in transparent oxyfluoride glass ceramics containing hexagonal NaErF4
(Elsevier B.V., 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 ...
Radiation-induced stable radicals in calcium phosphates: Results of multifrequency epr, ednmr, eseem, and endor studies
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
This article presents the results of a study of radiation-induced defects in various synthetic calcium phosphate (CP) powder materials (hydroxyapatite—HA and octacalcium phosphate—OCP) by electron paramagnetic resonance ...
Synthesis, structural and luminescent properties of Mn-doped calcium pyrophosphate (Ca2P2O7) polymorphs
(Nature Research, 2022)
In the present work, three different Mn2+-doped calcium pyrophosphate (CPP, Ca2P2O7) polymorphs were synthesized by wet co-precipitation method followed by annealing at different temperatures. The crystal structure and ...
Shortwave Ultraviolet Persistent Luminescence of Sr2MgSi2O7: Pr3+
(MDPI, 2023)
Currently, extensive research activities are devoted to developing persistent phosphors which extend beyond the visible range. In some emerging applications, long-lasting emission of high-energy photons is required; however, ...
Application of Calcium Aluminate Doped with Mn and Cr in Optical Thermometry
(Sciendo, 2023)
Optical thermometers are advantageous for temperature measurement in electromagnetic fields and aggressive environments; however, their composition mostly relies on materials doped with expensive and resource-limited rare ...
