Abstract
CdS and ZnS particles were synthesised inside some synthetic and natural zeolite frameworks by treating the calcined Cd 2+ or Zn 2+ ion exchanged forms with 1 molar aqueous solution of Na 2S. The absorption and photoluminescence emission spectra suggest that clusters interconnect to form well-defined aggregates with a behaviour intermediate between that of discrete clusters and the bulk semiconductor. The dynamics and the optical absorption are strongly influenced by the interface and host.
