The study of luminescence of rare-earth organic complexes sensitized Eu~(3+) complex in PMMA matrix using combinatorial method

摘要

A combinatorial approach has been utilized for researching the luminescence of rare-earth ions complexes (RE(DBM)_3.Phen, RE=Dy~(3+), La~(3+), Gd~(3+), Sm~(3+), Y~(3+)) sensitized Eu~(3+) complex in PMMA matrix. The results show that the La~(3+) complex has the maximum sensitization efficiency among these sensitization ions. The luminescent intensities increase as the Eu content increase in PMMA matrix. The Lau complex exhibits higher sensitization efficiency at lower Eu content in PMMA matrix. At a content of 5% Eu complex, the maximum sensitization efficiency of La~(3+) is more than 20 times.
