摘要：

Thulium and ytterbium co-doped double tungstate Yb3+,Tm3+: NaY(WO4)(2) single crystals were prepared by using RF-heating Czochralski (CZ) palling method. Its polarized transmittance spectra have been recorded in the region of 290-2000nm at room temperature. The energy levels transitions were assigned to the corresponding absorption line. The up-conversion luminescences at 793nm and 475mn were measured when the sample were pumped by 972nm LD and the energy transfer mechanism between Yb3+ and Tm3+ ions was analyzed.
