Investigations in the CuGaS[sub 2]-ZnS and AgGaS[sub 2] -ZnS Systems

Abstract

and form solid solutions over the entire range with some evidence for compound formation at . Emission under 3650Aå excitation shifts from green to red with increase in concentration. Samples with more than do not luminesce at room temperature but, at −195°C, fairly bright emission is observed with up to . is soluble in to about 5–10 mole%, above which separation of is observed. Emission under 3650Aå excitation shifts from the blue to yellow .
