The effect of pressure has been measured on the emission peak location and emission intensity for a series of phosphors of the form (Zn/sub x/Cd/sub 1-x/)S:Ag:Cl and (Zn/sub x/Cd/sub 1-x/)S:Cu:Cl. The results are qualitatively consistent with the donor--acceptor model. The emission peaks shift to higher energy with increasing pressure but the magnitude of the shift decreases with increasing fraction of Cd. The pressure shift of the absorption edge of CdS is also smaller than that for ZnS. The emission peak shift is always less than the shift of the edge for any given fraction of Cd. Large intensity decreases are observed with increasing pressure for each of the phosphors. The observed intensity changes can be related to changes in the donor binding energy with increasing Cd concentration.
