Tetragonal scheelite-like single crystals NaEr(WO4)2 (NEW) have been grown by using RF-heating Czochralski (CZ) method for the first time. X-ray powder diffraction experiments show that the crystal has the same structure as NaY(WO4)2 (NYW) and its unit cell parameters were calculated as a = b = 0.5199 nm, c = 1.1265 nm, and V = 0.3045 nm3. Differential scanning calorimetry shows that the NEW crystal melts at 1188.5 °C, which is lower than that of NYW crystal. Optical properties measurements show that NEW has intensive green luminescence emission at 551 nm pumped by LD with a wavelength of 974 nm, which is a potential for green laser emission running through up-conversion.
