Eu3+‐doped‐bismuth‐based phosphate glasses with chemical equation (60 − x)P2O5–20Bi2O3−10Na2CO3–10SrF2–xEu2O3 (PBNSEu), (where x = 0, 0.1, 0.5, 1.0, 1.5 and 2 mol%) were fabricated using the melt‐quenching method. Obtain X‐ray diffraction (XRD), energy‐dispersive X‐ray (EDAX), and Fourier transform infrared (FTIR) spectra were used to characterize the structure of the prepared PBNSEu glass. The J–O (Judd–Ofelt) intensity parameters (Ω2, Ω4) were estimated using photoluminescence emission spectra. When excited with a xenon lamp at λexc = 394 nm, the most intense red‐emission transition occurred at ~612 nm (5D0→7F2). J–O intensity parameters were used to calculate radiative properties, whereas the radiative branching ratio (βR), radiative transition probability (AR), radiative lifetime (τR), and total radiative transition rate (Aτ) were calculated for the transitions 5D0→7FJ (where J = 0–4) and were obtained in the emission spectra for europium ion‐doped in the current glass. Using the CIE1931 chromaticity coordinates axes, the colours of various concentrations of Eu3+ ion‐doped PBNS glass were evaluated using the emission spectra. Temperature‐dependent luminescence spectra were recorded for the optimized PBNSEu20 glass to calculate the activation energy. These results strongly suggested red components in w‐LEDs and visible display laser applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
