CaLaAlO4/LaAlO3: 0.5%Tm3+, xYb3+ upconversion phosphors were prepared via the combustion method. The Tm3+ dopant concentration was constant (Tm=0.5mol%), while the concentration of Yb3+ co-dopant was varied (Yb = 1 – 10 mol%). The X-ray diffraction

In this study Barium Lanthanum Aluminate BaLaAlO4 and BaLaAlO4:xEu red phosphors were produced at different x at.% Eu concentration (x = 0,1,3,5 and 7 at.% of Eu) by combustion synthesis method and post-annealing. The X-ray diffraction (XRD) patterns

This work reports on the synthesis and characterization of Y2O3:Eu3+ powders obtained by the hydrothermal method. We studied the influence of different pH values (7–12) and Eu3+ concentrations (2.5–25 mol%) on the structural, morphological and lu

Nowadays, the problem of water contamination causes the optimization of the processes carried out in wastewater treatment plants to improve the pollutants removal efficiency. In this work, an optical system was implemented to measure the sedimentatio
