The Nd-doped yttria and lanthanum yttrium oxide transparent ceramics were fabricated and their spectroscopic properties were investigated. Compared with Nd: Y2O3, all absorption bands of 2% Nd:(Y0.9La0.1)(2)O-3 are broadened. The full width of half-maximum(FWHM) at 806 nmis about 8 nm and the absorption cros-ssection is 1.742 x 10(-20) cm(2). According to the Judd-Ofelt theory, its emission cross-section at 1079nm is 3.378 x 10(-20) cm(2) and the measured fluorescence lifetime (tau(s)) is 98.4 mu s. (c) 2008 Elsevier B. V.
