MgF2:Mn2+: novel material with mechanically-induced luminescence

Jingjing Ning et al.

Summary: Mechanoluminescent (ML) materials can convert external mechanical stimulation into light, making them potentially useful in various areas. Currently, reproducible ML materials are mainly limited to sulfide- and oxide-based materials. This study presents a novel ML material, MgF2:Mn2+, which emits bright red light under external dynamic force without the need for pre-charging with UV light. Additionally, a highly transparent ML film incorporating MgF2:Mn2+ into polydimethylsiloxane (PDMS) matrices was successfully fabricated.

Luminescence in the LiF-MgF2 System Activated by Rare Earths

V. S. Singh et al.

Summary: The existence of LiMgF3 as a luminescent material has been confirmed to be non-existent, likely belonging to a frozen eutectic or two-phase system. By utilizing the lower melting point of a eutectic, it is possible to prepare various MgF2-based phosphors at temperatures as low as 735 degrees Celsius, against the high melting point of 1263 degrees Celsius for MgF2.

Ab Initio Computations of O and AO as well as ReO2, WO2 and BO2-Terminated ReO3, WO3, BaTiO3, SrTiO3 and BaZrO3 (001) Surfaces

Roberts Eglitis et al.

Summary: In this study, surface relaxation and rumpling computations were performed for ReO3, WO3, SrTiO3, BaTiO3, and BaZrO3 (001) surfaces using a hybrid B3LYP or B3PW exchange and correlation description. The results showed that the upper layer atoms on the surface shifted towards the bulk, the second layer atoms shifted upwards, and the third layer atoms shifted downwards. Additionally, the surface Gamma-Gamma bandgaps were found to be smaller than the bulk Gamma-Gamma bandgaps.

On the origin of precipitation of transition metals implanted in MgO

Debolina Misra et al.

Summary: This study uses density functional theory calculations to show that the precipitation of implanted ions in a host lattice depends on factors such as formation energy, dopant site, barrier of transition, and diffusivity. The research reveals that while neutral iron in MgO migrates slowly, nickel ions in all charge states migrate rapidly at 600 K. This work provides a new approach for predicting the stability of implanted ions in stable rock-salt structured oxides.

Effect of 130 keV pulsed electron irradiation on the efficiency of radiative transitions in Eu-doped glass-ceramics CaSiO3

Carlos D. Gonzales-Lorenzo et al.

Summary: This study focused on the photoluminescent characteristics of Eu3+-doped polycrystalline glass-ceramic CaSiO3, with an investigation into the impact of pulsed corpuscular action of electrons on energy transitions in the Eu3+ ions. The results showed that exposure to an electron beam caused a redistribution of relative intensities of transitions in the photoluminescence spectra of europium, leading to a decrease in the symmetry of the crystal field around the Eu3+ ions. Discussions were also made on the reasons for the decrease in the relative intensity of the Eu3+ luminescence signal, including the effects of material electrization, intrinsic defects, and inhomogeneous phase composition.
