Summary: The composition of glass with 40% SiO2, 40% B2O3, 10% V2O5, (10-x)% Fe2O3, and x% Sm2O3 (where x = 0, 2, 4, 6 mol%) was prepared using the melt-quench technique. Various experimental methods such as X-ray diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, Raman spectroscopy, UV-visible spectroscopy, and vibrating sample magnetometer (VSM) were used to characterize the structural, optical, and magnetic properties of the as-prepared glasses. The addition of Sm2O3 increased the glass density nonlinearly, and the optical band gap was in the semiconducting range (2.2-2.6 eV). These glasses can potentially be used in hyperthermia treatment as thermoseeds.

Summary: Identifying interfacial properties and discussing optical properties of antimony-based type II superlattices are crucial for the development of infrared optoelectronic devices. In this study, a multi-epitaxy-layered structure of an infrared detector with an InAs/InAsSb superlattice as an active area layer was grown and examined. The results of various analyses, including X-ray diffraction, transmission electron microscopy, and differential phase contrast scanning transmission electron microscopy, confirmed the high quality and small lattice mismatches of the epitaxial layers. The photoluminescence spectrum demonstrated a strong photoluminescence signal at 5.4 μm at 75 K and 6.2 μm even at 320 K.

Summary: Hexagonal gadolinium Phosphate Hydrate doped with different amounts of europium (Gd1-xPO4:Eu-x•H2O; x = 0.01, 0.05, 0.10, 0.15, and 0.20) was synthesized by hydrothermal synthesis method. The optimal dopant concentration was determined through analysis. Additionally, gadolinium was replaced by Lanthanum Gd0.85-yLayPO4:15%Eu (y = 0.25, 0.5, 0.75) to potentially improve luminescence properties due to the monoclinic crystal structure of LaPO4. The crystal structure, morphology, surface area, pore size, and luminescence properties of the synthesized compounds were analyzed.
