首次生长具有白钨矿结构的NaEr（WO4）2晶体。测量得晶体在UV波段的截止波长为326 nm，比N aY（WO4）2　（321 nm）晶体要长。这是由于Er3＋具有较大的极化力造成的。测量了NaEr（WO4）2红外透过光谱和喇曼光谱，并对晶格振动模式进行了分析。所有这些性质和同结构的NaY（WO4）2晶体进行了比较。

Tetragonal scheelite-like single crys tals NaEr(WO4)2 (NEW) have been grwon by using RF-heating Czochralski (CZ ) method for the first time.Its transmittance spectrum was measured,comparing wi th that of NaY(WO4) (NYW) crystal,its cut-off wavelength at UV-band is long er than NYW.It is caused by the bigger polarizing ability of Er3＋ than Y3＋．The infrared transmittance and Raman spectra were also measured,the factor group analysis was made and the lattice vibration frequency was assigned.
