A combinatorial approach was used to systematically investigate the effect of trace Pr(3+), Tb(3+), or Sm(3+) on the VUV photoluminescence of Eu(3+) in the Pr(3+), Tb(3+), or Sm(3+) co-doped (Y(0.65)Gd(0.35))BO(3):E(3+)(0.05). We found that Pr(3+) and Tb(3+)increases the VUV photoluminescent efficiency, while Sm(3+) decreases the efficiency. The optimized composition was identified to be between 7 x 10(-6) and 3 x 10(-4), and the corresponding efficiency improvement is about 15%. Scale-up experiments confirmed the results in the combinatorial materials libraries.
采用组合方法系统研究了痕量Pr(3+)、Tb(3+)或Sm(3+)对Pr(3+)、Tb(3+)或Sm(3+)共掺杂(Y(0.65)Gd(0.35))BO(3):E(3+)(0.05)中Eu(3+)真空紫外光致发光的影响。我们发现Pr(3+)和Tb(3+)提高了真空紫外光致发光效率，而Sm(3+)降低了该效率。确定最佳组成在7×10^(-6)至3×10^(-4)之间，相应的效率提高约15%。放大实验证实了组合材料库中的结果。
