摘要
用光谱法测定了不同掺杂浓度的ZnWO_4:Cr^(3+)体系中Cr^(3+)离子的有效分凝系数;利用X射线分析研究了不同组分的ZnWO_4:Cr^(3+)晶体的晶胞参数变化;确定在掺Cr_2O_3量为0.05%时,晶胞体积最小。
The efficient distribution coefficient of Cr3+ ion in ZnWO4:Cr3+ system under different dopping concentrations have been investigated by emission spectroscopy method, it changes from k<1 to k>1, when the dopped Cr2O3 is about 0.05%(wt). At that dopping level, the volume of the unit cell of ZnWO4:Cr3+ measured by X-ray analysis is the minimum.
