摘要	Phase transformation during preparation of Y2-x-yGdxEuyO3 (x + y <= 2) nanoparticles by citric acid chelating and influence of pH value on the powder morphology were studied by XRD and SEM. The behavior of solid solution was analyzed through calculation of lattice parameters and unit cell volume of Y2-x-yGdxEuyO3 and its luminescence property was obtained. The results show that the appropriate condition to prepare cubic Y2-x-yGdxEuyO3 powder is that the pH value less than 3, calcining tit, 900 degrees C for 2 h. Y2-x-yGdxEuyO3 powders with spherical morphology and size of 90 nm can be prepared under the condition of pH=1 and adding a little amount of glycol (5%, volume fraction). Luminescence properties of the powders are affected by the ratio of Y, Cd and the content of En. The luminous intensity reaches the maximum value when the powder composition is Y0.2Gd1.65Eu0.15O3. Concentration quenching occurs when y is above 0.15 and then the emission intensity decreases.
