DEVELOPMENT OF GLAZE CONTAINING Eu3+ IONS FOR THE LUMINESCENT ARTWORK APPLICATION

In this work, the luminescent properties of opaque glaze sample containing Eu3+ ions were investigated. The results revealed that the major chemical composition consisted of SiO2 and Eu2O3 which corresponds to the XRD spectrum of glaze sample. The reflectance spectra exhibit photon absorbing of Eu3+ ions in the visible to near-infrared regions at 395, 465, 534, 2048, and 2191 nm. The luminescence spectra in the visible region, under the 395 nm excitation wavelength exhibited emissions at 578 nm (5D0 → 7F0), 593 nm (5D0 → 7F1), 611 nm (5D0 → 7F2), 651 nm (5D0 → 7F3) and 703 nm (5D0 → 7F4). The decay time for the 7F2 level of Eu3+ ions was also analyzed. Additionally, the CIE 1931 chromaticity diagram investigation found that the luminescence falls within the red-orange color region.
