Abstract
Ion-Beam-Induced Luminescence (IBIL) spectra and images for the chemical states and crystal structures of micrometer-sized mineral targets were obtained by wavelength-dispersive IBIL analysis. A wavelength resolution of approximately 2 nm was achieved with a remote-controlled compact monochromator installed on an IBIL analysis system using a 3 MeV H+ microbeam. Several particulate mineral targets and aerosol samples were prepared on a carbon-plate sample holder that was selected to reduce the background noise and achieve a high S/N ratio in both the IBIL and Particle-Induced X-ray Emission (PIXE) analyses. The chemical composition of small targets that could not be well determined using micro-PIXE analysis was successfully visualized by the proposed IBIL analysis.
