Microwave Synthesized Eu3+ Ion Phosphor-in-Glass: A Novel Scintillation Material with Enhanced Luminescence
The Gd2MoO6:Eu3+ phosphor-in TeO2: ZnO: BaO glass by microwave synthesized technique at different weights of phosphors (0.00, 2.50, 5.00, 7.50 and 10 wt%). The prepared samples were characterized through XRD, SEM, Raman, density, refractive index, absorption spectra, photoluminescence properties, and X-ray-induced luminescence. Crystalline structure was studied and compared with the Gd2MoO6 standard by using a Shimadzu XRD-6100 diffractometer. Absorption spectra were evaluated in the wavelength region between 400 and 2300 nm and found four peaks, which corresponded with the transitions of Eu3+ ion from 7F0 (ground state) → 5D2, 5D1, 7F6 and 7F1→7F6 at 464, 534, 2088 and 2203 nm respectively. Photoluminescence was recorded in the wavelength region of 550-725 nm using an excitation wavelength of 395 nm. The emission intensity of the prepared samples increased with the increasing weight of Gd2MoO6:Eu3+ phosphor. The Photoluminescence quantum yield of the highest intensity sample is 9.34 %. The luminescence lifetime from the 7F0 → 5D2 state decreased with increasing weight of phosphors, which had a lifetime of 0.993, 0.987, 0.998, and 0.981 ms respectively when monitored at λex = 395 nm. In addition, the X-ray-induced luminescence study showed that the intensity of the sample increases with increasing phosphor concentration. The results obtained in X-ray-induced luminescence found that the samples could be potential candidates for reddish-orange light-emitting for scintillation applications.
期刊介绍:
Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
