中文摘要	pbs clusters in zeolite-y have been prepared with the reaction of pb2+-ion-exchanged zeolite-y with na2s in solution at room temperature. their absorption spectra show dramatic blue shifts from that of the bulk pbs. obvious change of both the absorption edges and peak positions upon pbs concentrations have been observed. these phenomena provide evidences that pbs clusters have been formed within the zeolite. the absorption spectra show featureless structure and have no tails near the absorption edges. as the pbs loading density becomes higher, the absorption bands become stronger and sharpen. order pbs clusters lattice with high quality might be formed in the supercages of zeolite-y.
