Abstract:

Synthesis of polycrystalline Nd:Sr0.95Ba0.05WO4 by means of liquid- and solid-phase reaction was reported. X-ray powder diffraction results showed that the as-grown Sr0.95Ba0.05WO4 and Nd: Sr0.95Ba0.05WO4 single crystals belonged to tetragonal system and I4(1)/a space group. Transparent Nd:Sr0.95Ba0.05WO4 single crystal could be obtained along c-axis by Czochralski method from the synthesized polycrystalline material. As the transmittance of Sr0.95Ba0.05WO4 single crystal could reach 80%, Nd3+ ion was adopted to be doped into the single crystal. Spontaneous Raman spectrums of polycrystalline material and single crystal were measured by RERKZN-ELMER2000 and JY-HR800. B, using X-ray fluorescence method, the effective segregation coefficients of Nd, Ba, Sr, and W elements in Sr0.95Ba0.05WO4 single crystal were estimated as 0.844 (0.745), 0.44, 1.09, and 0.95, respectively. The segregation coefficients of Nd in Sr0.95Ba0.05WO4 were higher than that in BaWO4, and this is as better as a Raman laser crystal.
