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 La~(3+) 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.
