Summary: A series of SrGd2O4 samples doped with different concentrations of Sm3+ and Dy3+ were prepared through glycine-assisted combustion synthesis. X-ray Powder Diffraction investigation confirmed the presence of pure orthorhombic lattice SrGd2O4. Energy Dispersive X-ray Spectroscopy showed that the desired elements were incorporated in the structure. Field Emission Scanning Electron Microscopy revealed the morphology of the samples as porous aggregated particles consisting of approximately 50 nm-sized spherical particles. Mercury Intrusion Porosimetry demonstrated the presence of a real permanent 3D pore structure. X-ray Photoelectron Spectroscopy confirmed the successful incorporation of Dy3+ and Sm3+ ions. Down-conversion luminescence spectra showed typical emission transitions for Sm3+ and Dy3+ ions. The energy band gap of the doped samples was calculated to be 4.3 eV using UV-VIS Diffuse Reflectance Spectroscopy. UV-VIS Absorption Spectroscopy observed the photocatalytic degradation process, with approximately 50% of Rhodamine B being mineralized after 4 hours of simulated Sun exposure.

Summary: Bismuth (Bi) doped glasses and fibers have gained attention for their broad and long lived near infrared (NIR) emission. Codoping rare earth ions is a feasible way to modulate the NIR emission properties of Bi, but limited success have been achieved. By investigating nonactive rare earth (RE) codoped aluminoborate glasses, it is found that the addition of nonactive RE ions changes the glass structure and optical basicity, altering the optical properties of Bi.

Summary: Fluorescent anti-counterfeiting technology is widely used due to its simplicity, low cost, and high safety. However, the development of multi-mode and polychromatic fluorescent materials for advanced anti-counterfeiting still faces technical challenges. In this study, dual-mode polychromatic Cs2AgIn0.99Bi0.01Cl6 double perovskite nanocrystals (DPNCs) doped with Yb3+/Er3+ were developed. The DPNCs emitted bright yellow light under 365 nm UV light and green fluorescence under 980 nm laser excitation. Based on the dual-mode and polychromatic fluorescence characteristics, a high-level anti-counterfeiting method was designed using this material. The brightness of the anti-counterfeiting pattern based on this material showed minimal decrease after three months, indicating its potential application in information encryption and identity recognition.

Summary: This contribution presents a kinetic model aiming to reproduce the response of thermoluminescent material LiF:Mg,Cu,P to absorbed doses in the kGy range. The model is based on the hypothesis of a relationship between irradiation time (absorbed dose) and trapping/recombination center density. X-ray diffraction and thermal X-ray diffraction measurements were conducted to investigate potential radiation and thermal damage on the material's structure, with a proposed kinetic model qualitatively reproducing observed changes in the TL glow curve and absorbed dose response regions.

Summary: This paper presents experimental results on the structural, morphological, and luminescence characterization of Eu3+ doped BaZrO3 powders produced by the green synthesis method. BaZrO3 powders with a highly crystalized cubic structure were synthesized using the chemical hydrothermal method. The PL emission spectra of the BaZrO3 powders showed characteristic emissions of Eu3+ ion, and the luminescence efficiency was found to be the highest when the synthesis was performed with a 5 mol% Eu3+ concentration. The study also demonstrated the thermoluminescence properties of the BaZrO3:Eu3+ powders, showing two TL peaks at around 110°C and 235°C.

Summary: This paper investigates the thermal effect on the luminescence emission of paracetamol tablets exposed to ionizing radiation. The results show that the thermoluminescence emission remains stable, indicating no damage to the structure of paracetamol. The behavior observed suggests the existence of a continuum in the trap system, supported by the calculated activation energy values and the absence of lattice structure variation in thermally treated samples.

Summary: This paper presents the luminescence characterization of various dosimeters exposed to different types of radiation. The dosimeters show high sensitivity to both ionizing and partially ionizing radiation based on their luminescence properties. The chemical compositions of the dosimeters significantly affect their cathodoluminescence emission, and the dopant in CaF2 dosimeters leads to different luminescence spectra. The variation in thermoluminescence glow curves allows for discrimination between dosimeters exposed to beta and UVC radiation.
