Preparation and Properties of La₂O₃-CaO-P₂O₅ Glasses Doped with Eu³⁺ Ions

Abstract:

Lanthanum calcium phosphate glasses doped with Eu³⁺ ions in compositions 20La₂O₃:10CaO:(70-x)P₂O₅:xEu₂O₃ (where x = 0.05, 0.10, 0.50 and 1.50 mol%) were prepared by melt-quenching technique. The density and molar volume measurements were carried out at room temperature. The absorption spectra were investigated in the UV-Vis-NIR region from 200 to 2500 nm. The emission spectra of Eu³⁺-doped glasses centered at 590 nm (⁵D₀→⁷F₁), 612 nm (⁵D₀→⁷F₂), 652 nm (⁵D₀→⁷F₃) and 699 nm (⁵D₀→⁷F₄) have been observed with 393 nm excitation wavelength.
