Title
Time-resolved photoluminescence of terbium-doped microporous–mesoporous Zeotile-1 materials
Abstract

Time-resolved luminescence spectra and decays were analyzed for the as-synthesized (hydrated) as well as for the calcined terbium-exchanged microprous–mesoporous Zeotile-1 materials. On the basis of photoluminescence decays, peak and area normalized time-resolved photoluminescence spectra, one species for the hydrated terbium–Zeotile-1 and two species for the calcined terbium–Zeotile-1 materials were evidenced, respectively. Our results highlighted that combined information from both spectral- and time-domain could bring more reliable information on the lanthanide distribution in these highly heterogeneous materials.
