We have investigated the molar extinction coefficients (epsilon) and solubility Of UO2(beta-diketonato)(2)dmso (beta-diketonate = acetylacetonate (acac), trifluoroacetylacetonate (tfacac), and hexafluoroacetylacetonate (hfacac); dmso=dimethyl sulfoxide) in supercritical CO2 (scCO(2)) at 40 degrees C in the pressure range of 10-25 MPa (density; 0.6
