Quantum-Sized Silver Sulfide Clusters in Zeolite A. -The reaction of H 2 S with activated Ag + -loaded zeolite A leads to silver sulfide zeolite A composites (AgxS x/2 Na 12-x HxSi 12 Al 12 O 48 •nH 2 O). The optical absorption and emission spectra of samples with different loading densities of Ag 2 S strongly suggest the presence of small Ag 2 S clusters. The effect of the variation of the Ag 2 S content on the emission spectra is remarkable. The luminescence is blue-green for samples with low Ag 2 S content, yellow or orange at medium Ag 2 S content, and red at high Ag 2 S content. -(BRUEHWILER, DOMINIK;
