title: The sensitized emission of Eu3+ and Tb3+ by 4-fluorobenzophenone confined in zeolite L microcrystals.
abstract: Disc-shaped zeolite L crystals having a narrow size distribution were prepared and characterized. Luminescent materials were prepared by insertion of 4-fluorobenzophenone into the channels of Ln(3+)-exchanged zeolite L microcrystals via the gas diffusion method. The obtained materials were characterized by SEM, elementary analysis, diffuse reflectance spectroscopy and photoluminescence spectroscopy. Energy transfer from 4-fluorobenzophenone to Eu(3+) or Tb(3+) or to both Eu(3+) and Tb(3+) can occur in the channels. The emission color of the resulting materials can be tuned by varying the relative amount of Eu(3+) and Tb(3+).
