Abstract

Recent results on the structure and luminescence enhancement of Eu₂O₃, EuS, and ZnS:Mn²⁺ as well as photo-stimulated luminescence of Ag and AgI nanoparticles encapsulated in porous hosts are presented. Eu₂O₃ nanoparticles encapsulated in MCM-41 display different structures depending on the temperature used to form the guest-host material. Particles formed following heat treatment at 140°C show monoclinic structure with enhanced luminescence efficiency. This increased efficiency may originate from a decrease in the radiative lifetime of the emitter within the host cavity. Similarly, EuS and ZnS:Mn²⁺ show increased luminescence when encapsulated in zeolite-Y. Ag and AgI nanoparticles encapsulated in zeolite-Y show significant photostimulated luminescence with very short lifetimes. The appearance of strong photostimulated luminescence with short decay times demonstrates that nanoparticles encapsulated in porous host materials have potential for digital storage and medical radiology applications.
