In the present investigation, Swift Heavy Ion irradiation (SHI) has been successfully utilized to modify the structure and surface morphology of cobalt doped Hydroxyapatite (HAp) thick films for CO and CO2 gas sensing application. Nano-crystalline Co-HAp powder is used to prepare sensor matrix in the form of thick films by means of screen printing technique. Furthermore, Co-HAp thick films are irradiated using Ag7+ ions (100 MeV) with ion fluence of 3x1011 and 3x1013 ions/cm2. Structural...
