| Outline of Final Research Achievements |
Luminescent materials without containing rare-earth elements, silver ion-containing zeolites, that absorb ultraviolet rays and emit visible lights have been developed; the materials may serve to increase the amount of solar radiation for photosynthesis. Among the zeolite species tested, X- and Y-type zeolites showed strong luminescence. The coexistence of cations other than silver increased the fluorescence intensity; the coexistence of zinc ion in X type zeolite and coexistence of both barium ion and lithium ion in Y type zeolite was optimal. The fluorescence intensity at this time was higher than the commercially available YAG. In Y type zeolite, lower silver content showed higher luminescence . We also succeeded in producing nano-sized zeolites, but their fluorescence intensity was smaller than in the case of micron-sized zeolites. The coexistence of zinc ions and ammonium ions suppressed the oxidation reaction of the supported silver ions.
