摘要

Three series of luminescent silicone resins have been synthesized. This ternary resin (SiPy-La-L, La = Eu, Tb or Dy; L = 1, 10-phenanthroline or acetylacetone) is composed from the precursor, the second ligand and lanthanide ions using a sol-gel method. The precursor is derived from the hydrosilylation reaction of methyldichlorsilane and 4-vinylpyrodine. Lanthanide ions (Eu ~(3+), Tb ~(3+) and Dy ~(3+)) act as luminescent center. Structure and texture of silicone resins are characterized by the X-ray diffraction (XRD) and scanning electron microscopy (SEM). The luminescence of silicone resins are monitored and studied in detail. Red and green luminescences are checked when silicone resins are exposed to ultraviolet light, suggesting that the intra-molecular energy-transfer processes take place within these silicone resins.
