Outline of Final Research Achievements |
In this study, we have developed a new ion beam analytical technology of charged particle induced luminescence(IBIL) for individual analysis of airborne particles. IBIL has the possibility to visualize the distribution of organic and inorganics in compounds or on the surface of particles in scale of several micrometers. To enhance its applicability under general microbeam scanning condition, we developed a high resolution type visible light detector based on photo-multiplier tube array. Continuous analysis of IBIL disclosed significant change in the emission wavelength of IBIL from particulate targets as well as organic standards. Based on these experimental results, IBIL spectroscopy and imaging technique enabled to analyze or identify the chemical composition and changes in micrometer-scale targets.
