In this paper, the successful growth of novel tetratungstate crystal, Na5Tb(WO4)4, from a Na2WO4 flux is reported. The lattice parameters are calculated with the result of a=1.1452nm, c=1.1364nm, c/a=0.9923. Furthermore, the infrared, absorption, fluorescence and excitation spectra of Na5Tb(WO4)4 crystal are measured.
