摘要 | Uniform NaYF4: Yb3+,Er3+@NaYF4: x%Yb3+(x=0, 20, 40, 60) nanoparticles were synthesized through thermolysis in oleic acid and 1-octadecene. The upconversion luminescence of these core/shell nanostructures was explored at different temperatures (90-450 K). The results demonstrate that the emission at 525 nm(2H11/24I15/2) of core/inert-shell nanoparticles exhibites a different growth from that of core/active-shell nanoparticles. The upconversion emissions of Yb3+-doped-active-shell nanoparticles are more easily affected by phonons than those nanoparticles coated with inert layer. Yb3+ions in the shell paly an important role of bridging the iner and outer factors to influence upconversion emission. 2015, SCIENCE PRESS. All right reserved. |
