The photo- and thermally- stimulated luminescence of Gd2O3 and Gd2O3:Zn nanostructured powders has been investigated at 295 and 90K. Optically active impurities and intrinsic defects in the host lattice have been detected. The kinetics parameters of the charge trapping centers (order of kinetics, activation energy, frequency factor) were determined. The nature of defect states and their role in the...
Different phases of Eu 3+ activated gadolinium oxide (Gd (OH) 3 , GdOOH and Gd 2 O 3 ) nanorods have been prepared by the hydrothermal method with and without cityl trimethyl ammonium bromide (CTAB) surfactant. Cubic Gd 2 O 3 :Eu (8mol%) red phosphor has been prepared by the dehydration of corresponding hydroxide Gd(OH) 3 :Eu after calcinations...
