Electrical and optical characterization of green synthesized Gd₂S₃

Gadolinium sulphide (Gd₂S₃) is a magnetic semiconductor with large band gap. Gd₂S₃ was synthesized following chemical and green techniques. Later process provides good stability of the nano clusters (NC) due to in-situ capping of Gd₂S₃ NC. It has been found that the optical band gap in Gd₂S₃ developed by green synthesis is lowered considerably over that in chemically synthesized Gd₂S₃. The green agencies used in this work are Jatropha Latex and dilute Garlic extract; both are enriched in sulphur and other organic polymer molecules. Simple observation shows that Gd₂S₃ NC retains residual magnetization. In this work optical and electrical characterization of the developed Gd₂S₃ specimens are carried out. The overall results obtained are good.
