Na_2SiF_6对Er^(3+),Yb^(3+)共掺杂上转换发光材料颗粒度的影响

Effect of Na_2SiF_6 on Particle of Up-Conversion Luminescence Material

合成了Er3+,Yb3+共掺杂的纳米级上转换发光材料。针对稀土离子Er3+,Yb3+共掺杂上转换发光材料的制备过程,研究了络合剂和Na2SiF6对控制最终产物颗粒度的作用,指出络合剂和Na2SiF6的共同作用有利于合成出粒度分布比较均匀的纳米级上转换发光材料,讨论了Na2SiF6的作用机制,并简单阐述了上转换发光材料的发展和应用。

Er^(3+) and Yb^(3+) codoped nano up-conversion luminescence material were synthesized. In allusion to the synthetic process of Er^(3+) and Yb^(3+) codoped up-conversion luminescence material, the effect of and Na_2SiF_6 on its particle was studied. It is pointed out that the common function of the complex compound and Na_2SiF_6 is beneficial to synthesizing homogeneous nano up-conversion luminescence material. The acting mechanism of Na_2SiF_6 was disussed. The developments and applications of up-conversion luminescence was set forth.
