摘　　要：采用顶部籽晶生长法从K2Mo3O10 B2O3 助熔剂中生长出15 mm×15 mm×25 mm 优质TmxGd1-x Al3(BO3)4 (x= 1, 0. 06)晶体。利用X 射线单晶衍射仪测定了TmAl3 (BO3 )4 晶体的结构。对Tm3+:GAB晶体进行定向切割,测量得到了σ和π方向的偏振的吸收和发射光谱,并根据Judd Ofelt理论计算了Tm3+在GdAl3(BO3)4 中的J O参数、各个能级的振子强度、自发辐射几率、荧光分支比等参数。Tm1-xGdxAl3 （BO3）4 crystals were grown from the K2Mo3O10-B2O3 flux by the top-seeded solution growth （TSSG） method. The TmAl3 （BO3）4 crystal structure was measured. Tm^3＋ ..GAB was cut into samples in c-axis and polarized absorption and emission spectra were measured. Based on the Judd-Ofelt theory, the optical parameters were caleulated, such as intensity parameters, oscillator strengths, radiative transition, probabilities, radiative lifetime as well as the branching.
