    Here, provides a detailed and technical explanation of the process and techniques used in the creation and analysis of solid polymer electrolyte films. It starts by clearly introducing the materials sodium nitrate and tamarind seed polysaccharide and the method solution casting used to create the films. The paragraph then explains how different compositions were achieved by varying the weight percentages of the materials. It further highlights the analytical techniques employed, such as FTIR and XRD, which are crucial for understanding the molecular and atomic interactions within the films. Additionally, the inclusion of Differential Scanning Calorimetry (DSC) is well-explained as a tool for analyzing the thermal properties of the films, rounding out the scientific methods applied to the study. The technical language used is precise, and the overall structure is coherent and informative. The selected method to evaluate the electrical characteristics of the films, including conductivity and dielectric behavior, was AC impedance spectroscopy. Notably, the film containing 30% NaNO3 showed a decrease in crystallinity, suggesting a transition to an amorphous structure. The electrical conductivity of the mixture is measured to be 1.14 × 10−4 S cm−1 at 313 K. At a higher temperature of 373 K, the conductivity increases significantly, reaching 1.45 × 10−4 S cm−1, indicating a pronounced improvement with temperature. Dielectric analysis revealed that these films exhibited a high dielectric constant and loss at lower frequencies, with both properties decreasing as the frequency increased. In addition, the film with 30% NaNO3 exhibited a peak in the low-frequency dispersion as indicated by the electric modulus study. In contrast, both Mʹ and M" showed the lowest electric modulus values for the same composition, suggesting significant differences in their electrical properties despite the similar NaNO3 concentration.
  • Ho3+-doped strontium-aluminium-bismuth-borate glasses for green light emission

    Luminescence, 2014
    Strontium–aluminium–bismuth–borate glasses (SAlBiB) doped with different concentrations of Ho3+ were prepared using conventional melt quenching technique and their structural and optical properties investigated. X‐ray diffraction and scanning electron microscopy analysis were used to study the structural properties. Optical properties were studied by measuring the optical absorption and visible luminescence spectra. The Judd–Ofelt (J‐O) theory was applied to evaluate J‐O intensity parameters, Ωλ (λ = 2, 4 and 6). Using J‐O intensity parameters, radiative properties such as spontaneous transition probabilities (AR), branching ratios (βR) and radiative lifetimes (τR) were determined. From the emission spectra, a strong green emission nearly at 549 nm corresponding to the transition, 5S2(5F4)→5I8 was observed. Emission peak positions (λP), effective bandwidths (Δλeff) and stimulated emission cross‐sections (σp) were calculated for the observed emission transitions, 5F3→5I8, 5S2(5F4)→5I8 and 5F5→5I8 of Ho3+ in all the glass matrices. Chromaticity color coordinates were calculated using the emission spectra. The experimental results suggest that SAlBiB glass matrix with 1.5 mol% of Ho3+ has better emission properties.
