aking into account variation of heat conductivity of a noble gas up to 2500 oK, we have investigate effect of thermal conduction on sonoluminescence radiation. Results of our numerical simulation show that thermal conductivity plays an important role in the bubble evolution at the collapse with a remarkable effect on the bubble peak temperature and its chemical activity. Calculated intensity of light emission by thermal-bremsstrahlung mechanism shows that at fixed degassing conditions, light intensity increases with driving pressure as well as with noble gas atomic mass, which is in a close agreement with available experimental reports.
