K(Y1-xYbx)3F10 (x = 0-1) solid-solution nanocrystals embedded glass ceramics were fabricated via glass self-crystallization. Using Eu(3+) as a structural probe, the partition of lanthanide activators into the K(Y1-xYbx)3F10 lattice was evidenced. As a consequence, color-tunable upconversion luminescence from green to red was easily realized by modifying Yb(3+) content in the Er(3+)-doped nano-glass-ceramics.
通过玻璃自结晶法制备了嵌入K(Y1-xYbx)3F10（x = 0 - 1）固溶体纳米晶体的玻璃陶瓷。以Eu(3+)作为结构探针，证实了镧系激活剂在K(Y1-xYbx)3F10晶格中的分配。因此，通过改变掺铒纳米玻璃陶瓷中Yb(3+)的含量，可以轻松实现从绿色到红色的颜色可调上转换发光。
