Structural and luminescence studies of europium ions in lithium aluminium borophosphate glasses

Synthesis of Eu3+-activated BaMoO4 phosphors and their Judd–Ofelt analysis: Applications in lasers and white LEDs

“…The trend of r e for the 5 [29] and Eu 3+ ions in lithium aluminium borophosphate glasses [32]. The higher stimulated emission cross section value was an attractive feature for low threshold and high gain laser applications which were used to claim good laser action [29].…”

Influence of Eu³⁺ dopant on physical and optical properties of lithium-borosulfophosphate glasses

“…Density measurements were made by using standard Archimedes method with toluene as immersing fluid (Hua et al, 2013, Wong et al, 2014, Reddy et al, 2016. The optical absorption spectra for all Eu3+-doped samples were obtained at room temperature using Shimadzu 3101 UV-Vis-NIR spectrophotometer in the range of 200 -2400 nm.…”

“…However, these glasses have a relatively poor chemical durability that often limits their usability. Several authors attest that the chemical durability of phosphate glasses can be improve by addition of various oxides either network former, modifier or intermediate (Wong et al, 2014.…”

“…In addition, the drawbacks such as high phonon energy and hydroscopic nature of borophosphate host matrix can be overcome by introducing modifier reagent into the host network to improve the intensity, disrupt the lattice, open the network structure, weakened the bond strength, and lowered the viscosity of host matrix (Pang et al, 2014). In this work, lithium is added as modifier to decrease the phonon energy, hygroscopic properties and improve the strength of the host (Wong et al, 2014).…”

Synthesis, structural characterization, and photoluminescence properties of Eu3+‐doped Mg3‐xEux(BO3)2 phosphor

“…Eu 3+ ion is one of the most popular and efficient dopant to use for a wide range of applications such as laser and luminescent materials because europium ions show good emissions related to electronic transitions of 4f orbitals corresponding to the 5 D 0 ? 7 F J (J:1,2,3,4) transitions, [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] because of these transitions, the Eu 3+ -doped compounds have the high luminescence efficiency. Moreover, magnesium borates are good candidates as host structure owing to their low synthetic temperature and simple preparation process.…”
