Abstract This paper reports a systematic study of distribution coefficient in YVO4 for the entire series of trivalent rare-earth dopants (RE = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Sc). For this aim, single crystals for each RE dopant were flux-grown under a fixed condition, with the starting ratio of Y0.9RE0.1. The compositions of the grown crystals were then determined using inductively coupled plasma emission spectroscopy. The distribution coefficient is close to 1 when the size mismatch between the dopant ion and the host Y3+ ion is within about ±3%, and drops off in a similar manner for both larger and smaller dopants. The distribution coefficients for the largest (La3+) and smallest (Sc3+) dopants are 0.2 and 0.07, respectively.

YVO4晶体中稀土掺杂剂分布系数的离子尺寸依赖性

摘要 本文报道了整个系列三价稀土掺杂剂（RE = La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb）在 YVO4 中的分布系数的系统研究。 、卢和 Sc）。为此，每种稀土掺杂剂的单晶在固定条件下助焊剂生长，起始比例为 Y0.9RE0.1。然后使用电感耦合等离子体发射光谱测定生长晶体的组成。当掺杂剂离子和主体 Y3+ 离子之间的尺寸失配在大约 ±3% 以内时，分配系数接近 1，并且对于较大和较小的掺杂剂以类似的方式下降。最大 (La3+) 和最小 (Sc3+) 掺杂剂的分配系数分别为 0.2 和 0.07。
