Osseointegrated implants for orbito-facial prostheses: Preoperative planning tips and intraoperative pearls.

Purpose: Implant-retained facial prostheses are becoming increasingly sophisticated. We describe our experience with successful implant placement.

Methods: Retrospective case series.

Intermolecular interaction and a concentration-quenching mechanism of phosphorescent Ir(III) complexes in a solid film.

Solid-state self-quenching processes of highly efficient Ir(III) phosphorescent emitters are investigated by the measurement of thin film photoluminescence quantum efficiency and transient lifetime as a function of doping concentration in a host matrix. The radiative decay rate constant is found to be independent from the average distance between dopant molecules (R), and the concentration-quenching rate constant is shown to be dependent on R(-6). The quenching dependence on R strongly suggests that luminescent concentration quenching in a phosphorescent Ir(III) complex:host film is controlled by dipole-dipole deactivating interactions as described by the Förster energy transfer model.
