  • Title: [Synthesis of a novel rare earth light conversion agent and study on its compatibility in plastics].
    Author: Xiao ZH, Tan ST, Wang XY, Zou YP.
    Journal: Guang Pu Xue Yu Guang Pu Fen Xi; 2005 Jan; 25(1):145-8. PubMed ID: 15852841.
    Abstract:
    2-octyl-1, 3-diphenol-1, 3-propdione was synthesized by phase transfer catalysis and its Sm complexes were prepared. These compounds were characterized by IR, EA, UV and 1H NMR; Sm complex and its mixture doped with PE and PVC show photoluminescence at 650 nm. There is excellent compatibility between Sm complex and plastics by the addition of long carbon chain. Therefore, Sm complex with long carbon chain is a superior light conversion agent with good compatibility in resins with emission wavelength suitable to the 643 and 660 nm for plants' photosynthesis.
