Abstract

Dy³⁺ ions doped Tungsten Alkali Borate (TAB) glasses were synthesized by conventional melt-quench technique and characterized for photonic device and radiation shielding applications. The structural analysis was done through XRD and FT-IR measurements. From the FT-IR spectra, the OH content present in the as prepared glass samples has been estimated and it is relatively low compared with other glasses. The Judd-Ofelt (J-O) theory was utilised to validate the experimental results and to evaluate the radiative parameters of the glasses. The effect of local ligand field environment around Dy³⁺ ions has also been understood from J-O intensity parameters. In the photoluminescence (PL) spectra, three emissions in bluish (⁴F_9/2 → ⁶H_15/2), yellowish (⁴F_9/2 → ⁶H_13/2) and reddish (⁴F_9/2 → ⁶H_11/2) regions were observed. A range of radiative properties along with CIE co-ordinates were measured to identify the optimum glass suitable for solid state device applications. Number of radiations shielding parameters were calculated to know the appropriate glass for x-ray and gamma rays shielding applications.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
