Abstract: 

Ion beam analysis (IBA) has been widely used for fast, sensitive, multi-elemental and nondestructive analysis without any sampling, especially for the pigment analysis. External beam PIXE and PIGE techniques are applied simultaneously to large archaeological samples, kept at atmospheric pressure during the irradiation. In this research work, an external beam was used for the analysis of lapis lazuli samples and the azure color of the archaeological tile. By comparing the spectra, we found that cobalt is used to create azure color in archaeological tiles, while in lapis lazuli, no cobalt is observed and sodium is the characteristic element of the azure color in the lapis lazuli samples. It was also shown that lapis lazuli can be identified by the ion beam analysis.
