Abstract
Sensing characteristics of Ho (1, 3 and 5% mol) - doped Bi2O3 clad-modified fibre optic gas sensor are studied for ammonia, ethanol, methanol and acetone gases at ambient temperature. Bi2O3 doped with all concentrations of Ho shows good gas response to acetone, whereas, 1% and 3% mol of Ho show to methanol. Ammonia and ethanol show very poor gas response for all the doping concentrations. The highest gas sensitivity and gas selectivity property are shown with 3% mol of Ho with acetone. Time response characteristics of the sensor are also reported.
