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 Ln3+-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 Eu3+ or Tb3+ or to both Eu3+ and Tb3+ can occur in the channels. The emission color of the resulting materials can be tuned by varying the relative amount of Eu3+ and Tb3+.
