用提拉法生长了ZnWO{sub4}：Ho{sup3+}单晶。给出了它们的X射线衍射谱、吸收光谱、荧光光谱，得到了它们的J-O强度参数分别为：4.61×10~(-20)cm~(-2)，0.16×10~(-20)cm~(-2)，0.48×10~(-20)cm~(-20)cm~(-2)。计算了不同跃迁能级下的辐射跃迁速率、分支比和辐射寿命。与543 nm跃迁{sup 5}S{sub2}{屈服}{sup 5}i{sub8}相关联的最强谱线有可能用于绿色固体激光器，该能级的荧光寿命为14.1{u}S。
The single crystal of ZnWO{sub 4}:Ho{sup 3+} was grown by Czochralski technique. The XRD, absorption spectra, fluorescence spectrum are presented, and the Judd-Ofelt (J-O) intensity parameters {omega}{sub 2}, {omega}{sub 4}, {omega}{sub 6} are obtained to be 4.61 x 10{sup -20} cm{sup 2}, 0.16 x 10{sup -20} cm{sup 2}, 0.48 x 10{sup -20} cm{sup 2}, respectively. Calculated radiative transition rate, branching ratios, and radiative lifetime for different transition levels of ZnWO{sub 4}:Ho{sup 3+}crystals are presented. The most intense line correlative with the transition {sup 5}S{sub 2} {yields} {sup 5}I{sub 8} at 543 nm is potentially used for green solid state laser, and the fluorescence lifetime of this energy level is 14.1 {mu}s.
