Abstract
A soft-chemical method has been developed for the synthesis of nano-crystalline powders of silver decamolybdate . Gas sensing characteristics of this composition both in porous pellet and thin film configurations were investigated. The compound Ag 6 Mo 10 O 33 was found to sense selectively ammonia at 503 K. Above 503 K it has significant cross sensitivity to petroleum gas (PG) . Spin coated thin films exhibited selective sensing towards PG.
