Chemical Tuning, Pressure, and Temperature Behavior of Mn Photoluminescence in GaO-AlO Alloys.

In this study, we carried out a detailed investigation of the photoluminescence of Mn in GaO-AlO solid solutions as a function of the chemical composition, temperature, and hydrostatic pressure. For this purpose, a series of (AlGa)O:Mn,Mg phosphors ( = 0, ..

AlO co-doped with Cr and Mn, a dual-emitter probe for multimodal non-contact luminescence thermometry.

Luminescence probes that facilitate multimodal non-contact measurements of temperature are of particular interest due to the possibility of cross-referencing results across different readout techniques. This intrinsic referencing is an essential addition that enhances accuracy and reliability of the technique. A further enhancement of sensor performance can be achieved by using two luminescent ions acting as independent emitters, thereby adding in-built redundancy to non-contact temperature sensing, using a single readout technique.

Structure Peculiarities of Micro- and Nanocrystalline Perovskite Ferrites La Sm FeO.

Micro- and nanocrystalline lanthanum-samarium ferrites La Sm FeO with orthorhombic perovskite structure were obtained by using both solid state reactions (x = 0.2, 0.4, 0.
