摘　　要：Single crystal Er:LuAl_(3)(BO_(3))(Er:LuAB)is successfully grown using the top-seeded solution growth method wlth 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)Å,c=7.210(3)Å,V=537.65(27)Å^(3),and Z=3.The absorption spectrum is measured at room temperature.The spectroscopy properties axe investigated based on the Judd Ofelt(J-O)theory,and the effective J-O parameters were calculated to beΩ_(2)=8.33×10^(-20),Ω_(4)=3.83×10^(-20),andΩ_(6)=3.55×10^(-20).The emission spectra of Er:LuAB crystal at room temperature are also studied and the^(4)I_(11/2)→^(4)I_(13/2)fluorescence around 3170nm is observed.The emission cross section calculated by the F-L formula is 8.6×10^(-20)cm^(2).These results suggest that the Er:LuAB crystal may be a promising-3μm laser material.
