摘要：Single crystal Er:LuAl3 (BO3) (Er:LuAB) is successfully grown using the top-seeded solution growth method with a K(2)MO(3)O(10 )flux. The cell parameters of the grown crystal are estimated by an x-ray single crystal diffactometor and x-ray powder diffraction analysis. The result indicates that it still belongs to the space group R32. The obtained unit-cell parameters are a = 9.2793(19) angstrom, c = 7.210(3) angstrom, V = 537.65(27) angstrom(3), and Z = 3. The absorption spectrum is measured at room temperature. The spectroscopy properties are investigated based on the Judd-Ofelt (J-O) theory, and the effective J-O parameters were calculated to be Omega(2) = 8.33 x 10(-20),Omega(4) = 3.83 x 10(-20), and Omega(6) = 3.55 x 10(-20). The emission spectra of Er:LuAB crystal at room temperature are also studied and the I-4(11/2) -> I-4(13/2) fluorescence around 3170nm is observed. The emission cross section calculated by the F-L formula is 8.6 x 10(-20) cm(2). These results suggest that the Er:LuAB crystal may be a promising ( )similar to 3 mu m laser material.
