Investigation of Spectroscopic Parameters and Trap Parameters of Eu<sup>3+</sup>-Activated Y<sub>2</sub>SiO<sub>5</sub> Phosphors for Display and Dosimetry Applications
Using the solid-state reaction technique, varied Y<sub>2</sub>SiO<sub>5</sub> phosphors activated by europium (Eu<sup>3+</sup>) ions at varied concentrations were made at calcination temperatures of 1000 °C and 1250 °C during sintering in an air environment. The X...

| description | Using the solid-state reaction technique, varied Y<sub>2</sub>SiO<sub>5</sub> phosphors activated by europium (Eu<sup>3+</sup>) ions at varied concentrations were made at calcination temperatures of 1000 °C and 1250 °C during sintering in an air environment. The XRD technique identified the monoclinic structure, and the FTIR technique was used to analyze the generated phosphors. Photoluminescence emission and excitation patterns were measured using varying concentrations of Eu<sup>3+</sup> ions. The optimal strength was observed at a 2.0 mol% concentration. Emission peaks were detected at 582 nm and 589 nm for the <sup>5</sup>D<sub>0</sub>→<sup>7</sup>F<sub>1</sub> transition and at 601 nm, 613 nm, and 632 nm for the <sup>5</sup>D<sub>0</sub>→<sup>7</sup>F<sub>2</sub> transition under 263 nm excitation. Because Eu<sup>3+</sup> is naturally bright, these emission peaks show how ions change from one excited state to another. This makes them useful for making phosphors that emit red light for use in optoelectronics and flexible displays. Based on the computed (1931 CIE) chromaticity coordinates for the photoluminescence emission spectra, it was determined that the produced phosphor may be used in light-emitting diodes. The TL glow curve was examined for various doping ion concentrations and durations of UV exposure levels, revealing a broad peak at 183 °C. Using computerized glow curve deconvolution (CGCD), we calculated the kinetic parameters. |
