Nd3+ substituted nanocrystalline zinc ferrite sensors for ethanol, LPG and chlorine

摘要：

　　Nd3+ substituted zinc ferrites with chemical formula ZnNdxFe2-xO4 (x =0,0.01,0.02,and 0.03) were prepared by oxalate co-precipitation method and characterized by XRD,IR and SEM techniques.The gas sensing properties were studied for ethanol,LPG and chlorine.It was observed that nanocrystalline ZnFe2O4 shows maximumsensitivity to ethanol (~41%) followed by LPG (~22%) and less sensitivity to Cl2 (~10%) at an operating temperature of 327℃.The sensitivity of zinc ferntes increases with increase m Nd3+ content.Response-recovery times of zinc ferrite decreases with increase in Nd3+ content.
