  • 在化学计量的熔料里,用提拉法生长了K5Bi0.9Er0.1(MoO4)4单晶。该晶体属于三方晶系,空间群为R3m,z=1.5,晶胞参数为a=6.029?,c=20.823?(六方表示)。晶体具有层状结构,沿着(0001)面容易解理。晶体在室温下的吸收光谱包括有若干条吸收带,它们是稀土离子所特有的。其中三个主要的吸收峰分别相当于从Er3+离子的基态 4I15/2向 4G11/2, 2H11/2和 4I13/2能级的跃迁。本文还给出晶体中相当于 4I13/2→ 4I15/2跃迁的荧光发射光谱。
    Single crystals of 5Bi0.9Er0.1(MoO4)4 were grown from stoichiometric melts by the usual Czochralski technique. The crystal belongs to trigonal system, with space group R3m , z=1.5, and cell parameters a=6.029?, c=20.823? (hexagonal setting). Due to the layered structure, the crystals exhibit easy cleavage along (0001) face. The room temperature absorption spectrum of 5Bi0.9Er0.1(MoO4)4 consists of severalbands characteristic for the rare earth ions in crystals. The spectrum is dominated by three absorption bands associated with transition from the ground 4I15/2 level of Er3+ to the 4G11/2, 2H11/2 and 4I13/2 levels, Details of room temperature emission Spectra Corresponding to the 4I13/2→4I15/2 transition are also given.
