In this work, we present an alternative approach to sensitize the near infrared emission of Er3+ ions (used in telecom applications) by exploiting the geometrical confinement occurring in porous zeolites structures. The sensitization of the Ln ion is obtained by energy transfer between a suitable organic molecule acting as an antenna and the emitting ion arranged in closed proximity, thus, avoiding the limits imposed by the coordination chemistry.

Abstract
In this work, we present an alternative approach to sensitize the near infrared emission of Er3+ ions (used in telecom applications) by exploiting the geometrical confinement occurring in porous zeolites structures. The sensitization of the Ln ion is obtained by energy transfer between a suitable organic molecule acting as an antenna and the emitting ion arranged in closed proximity, thus, avoiding the limits imposed by the coordination chemistry.
