Effect of Fe Doping on the Structural, Morphological, Optical, and Magnetic Properties of Ca2InTaO6 Double Perovskite

physica status solidi (b), EarlyView.
Fe‐doped Ca2InTaO6 double perovskites are synthesized via solid‐state reaction and systematically investigated. Rietveld refinement confirms orthorhombic Pbnm structure, while optical studies reveal a bandgap narrowing from 3.31 to 2.84 eV. Photoluminescence spectra exhibit strong red emission at 671 nm with optimal intensity at 10 mol% Fe ...

Breaking Concentration Quenching for Excellent Highly Efficient and Stable Narrowband Luminescence by Structural Ordering and Defect Regulation

Rare Metals, EarlyView.
ABSTRACT Enhancing the performance of phosphor materials for wide‐color‐gamut and high‐brightness phosphor‐converted light‐emitting diodes (pc‐LEDs) represents a critical materials challenge. Improving quantum efficiency (QE) under concentration quenching constraints and maintaining thermal stability remain primary objectives.

Cu‐Enhanced Medium‐Entropy TiZrCoCrMo Alloys: Balancing Superior Antibacterial and Osteogenic Properties for Orthopedic Implants

Rare Metals, EarlyView.
ABSTRACT This study introduces novel nonequiatomic TiZrCoCrMoCux (x = 0, 5, 10; at%) medium‐entropy alloys (MEAx) tailored for orthopedic implants, synergistically combining the biocompatibility of Ti‐based alloys, the wear resistance of CoCrMo alloys, and the antibacterial/osteogenic attributes of Cu. The alloy's microstructure, mechanical properties,

160 GHz Schottky Diodes from Solution‐Processed IGZO

Small, EarlyView.
A simple, scalable method for contact engineering of planar asymmetric nanogap electrodes enables the development of Schottky diodes with a cut‐off frequency of 160 GHz. Applying these diodes to radio‐frequency rectifying circuits yields output voltages in the range of 0.3–0.74 volts.

Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...
