Summary: In this study, a series of A'AEu(MO4)(3) compounds were synthesized and characterized using PXRD, FTIR, Raman spectroscopy. The tungstate compounds exhibited larger band-gaps compared to the molybdate compounds. Photoluminescence properties were affected by cations, with silver-containing compounds showing superior performance when excited by 395 nm light. The molybdate compounds demonstrated better photoluminescence properties due to higher covalence of Eu-O bond.

Summary: A series of green radiating terbium activated SrGdAlO4 nanocrystalline phosphors have been manufactured using a facile and ecological method. The nanocrystalline phosphors exhibit pure tetragonal phase with small agglomerated particles and show vivid green emission attributed to the transition of Tb3+ ions. The doping of Tb3+ ions enhances the luminescence efficiency and color purity of the nanophosphors, making them promising for white light-emitting diodes.

Summary: Cu1-xWxO nanostructures with different doping levels (x = 0.0, 0.01, 0.02, and 0.04) were characterized and their magnetic properties were analyzed. The presence of a minor WO3 secondary phase was observed in the x = 0.02 sample, and this secondary phase became necessary to include in the refinement for higher doping levels. Changes in IR bands were attributed to lattice variations and crystal defects. XPS confirmed the presence of W6+ in the W-doped CuO. The ferromagnetic response increased for the x = 0.01 sample, but decreased with increasing tungsten concentration until 4%. The remarkable magnetic characteristics of the x = 0.02 material were not explained solely by the presence of WO3 secondary phase.

Summary: Cost effective SILAR method was used to deposit ZnO thin films on glass substrates for thin film UV photodetector applications. The film properties such as structure, morphology, optical and electrical properties were investigated in detail with respect to the cationic precursor molarity. The increase in solution molarity resulted in an increased crystallite size and nearly stoichiometric composition of the films. SEM images showed the presence of rod or needle-like structures in the films. The films exhibited modified optical energy band gap and reduced defect states at higher molarities, leading to enhanced UV emission.

Summary: This report discusses the temperature-induced variation in the phonon properties and the spatial variation in the Raman spectra for spray-deposited Zn0.98Mn0.02S thin films. The novelty of this work lies in the study of the temperature dependence of the Raman line position, line width, and phonon lifetime using theoretical models that consider thermal expansion and three- and four-phonon anharmonic effects. The lifetime of the LO phonon in the Zn0.98Mn0.02S thin film was as low as 0.234 ps, indicating its suitability for optical limiting applications. The intensity ratio I-2LO/I-1LO ranges around 0.5 in most (x, y) positions in the Raman mapping data, suggesting the nanocrystalline nature of Zn0.98Mn0.02S.

Summary: The present research focuses on the properties of p-Si/ ZnSxSe1-x heterojunctions in photodetector applications. The heterostructures were fabricated by depositing ZnSSe on Si wafer using thermal co-evaporation technique. GIXRD study showed that the films were in cubic phase and the prominent peak shifted with composition x. Photoluminescence confirmed the presence of point defects and emission related to higher Zn content in the films. Temperature-dependent Raman analysis revealed the shift of longitudinal optical phonon modes with decreasing temperature, which described the variation of lattice parameters. The photoresponse of p-Si/ ZnSxSe1-x heterostructures was investigated and found that the sample with x = 0.8 exhibited high photosensitivity and is suitable for photodetector applications.

Summary: The spectral power distribution (SPD) is influenced by electrical and thermal loading and plays a significant role in evaluating the performance of LED lighting. Statistical models are commonly used for SPD prediction, but become complex and time-consuming with more than two inputs. Artificial Neural Network (ANN) models offer a solution to this problem. This study aims to enhance the practicality of ANN in lighting applications, utilizing different neural network structures (models 1, 2, and 3) to forecast SPD under various electrical and thermal stress levels at zero hours. Model 1 is identified as the best SPD prediction model based on the absolute prediction error (APE) set at 5%, and its time-based SPD prediction for LED luminaires is validated using temperature, wavelength, and time as input parameters.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
