Abstract
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 613Â nm, 584Â nm and 467Â nm were recorded as the function of dopant ion concentration. It was observed that the blue emission quenched at 1Â mol% Eu3+ whereas red and green quenched after 2Â mol% of Eu3+.
