Description 284-296
In this work, a chemical reaction technique has been employed to synthesize CdSe nanoparticles and CdSe/ZnO nanocomposites.
The synthesized samples have been characterized by different characterization methods. Study of selectivity of
the synthesized samples towards different gases such as ammonia, acetone, methanol, formaldehyde and ethanol has been
carried out. The synthesized CdSe and CdSe/ZnO samples have been found to be more selective towards methanol gas. As
such, gas sensing ability of both CdSe and CdSe/ZnO samples towards methanol gas has been investigated. It is observed
that, CdSe/ZnO nano composites have been more sensitive towards methanol gas as compared to CdSe nanoparticles.
