Abstract
The photoluminescence spectra of the Y-type zeolite modified with tita nium ions and Ti-silicalite-1 have been investigated by varying the ex citation energy. A three-dimensional image of the photoluminescence sh ows that the peak attributed to tetrahedral titanium oxide species is present at the excitation energy around 200-210 nm, which is consisten t with the UV absorption of the samples. The technique enables the dis tinction of the photoluminescence of the titanium species from that of silicate species.
