Nuclear magnetic resonance study of metallic scandium chlorides [PDF]

, 1978
The /sup 45/Sc nuclear magnetic resonance was studied in samples having the general composition CsSc/sub x/Cl/sub 3/ (0.67 less than or equal to x less than or equal to 1.0) in the CsCl-ScCl/sub 3/-Sc system. In particular the structure of CsScCl/sub 3/ suggests that it may be a one-dimensional conductor, and an attempt was therefore made to detect the

An Examination of the Cs2NaInCl6 Luminescence: Interplay of Self‐Generated In+ and Doped Sb3+, Er3+/Yb3+ Ions

Advanced Optical Materials, EarlyView.
A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Structural and Compositional Effects on the Scintillation Properties of Fast Emitting Metal‐Organic Frameworks

Advanced Science, EarlyView.
The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...
