Tuning of photoluminescence emission properties of Eu3+ doped Gd2O3 by different excitations

In this work, we investigated cubical particles of europium doped gadolinium oxide based material for colour tuning by different excitations. Structural properties of the material were studied by transmission electron microscopy and X-ray diffraction analysis. The Photo-luminescence (PL) technique was used to study luminescent properties of the material and its optical features were thoroughly investigated by calculating CIE chromaticity. Effect of Eu3+ concentration on emission spectra for three excitations was also recorded. The emission intensity for 613 nm, 584 nm and 467 nm were recorded as the function of dopant ion concentration. It was observed that the blue emission quenched at 1 mol% Eu3+ whereas red and green quenched after 2 mol% of Eu3+.
