摘要: Abstract A method for thickness determination of thin amalgamable metallic films by total-reflection X-ray fluorescence (TXRF) is presented. The peak’s intensity in TXRF spectra are directly related to the surface density sample, i.e. its a homogeneous film. Performing traditional analysis on film an amalgamated metal, and determining relative peak specific metal line, layer can be precisely obtained. In case gold determination, mercury peaks overlap, hence we have developed general data processing scheme achieve most precise results.
