摘要：
Orthorhombic terbium molybdate, beta'-Tb-2(MoO4)(3), microcrystals have been fabricated by solid state synthesis at T = 750-1270 K for t = 290 h. The crystal structure beta'-Tb-2(MoO4)(3) has been refined by Rietveld method in space group Pba2 with cell parameters of a = 10.35387(6), b = 10.38413(6) and c = 10.65695(7) angstrom (R-B = 1.83%). About 40 narrow Raman lines have been observed in the Raman spectrum recorded for the beta'-Tb-2(MoO4)(3) powder sample. The luminescence spectrum of beta'-Tb-2(MoO4)(3) has been measured under the excitation at 355 nm, and the intensive photoluminescence band at 540-550 nm has been found. (C) 2013 Elsevier B.V.
