摘要：
SnO2 thin films synthesized by sol-gel are irradiated with reactor neutrons up to fast neutron fluence of 9.6 x 10(17) neutrons cm(-2) at 40A degrees C. The influence of defects generated by neutrons irradiation, through the properties modification, on the photo-catalytic activity of SnO2 films is investigated. It is found that the photoactivity of the irradiated films is enhanced after reactor neutrons irradiation. An improvement of 41% is observed for the sample irradiated at a neutron fluence of 9.6 x 10(17) neutrons cm(-2). This is attributed to several parameters modified by the reactor neutron irradiation principally the crystallite size and space charge region which are closely related to the photocatalytic performance.
