An new ion micro-beam imaging technique was developed by using Ion-Beam-Induced Luminescence (IBIL) analysis system. IBIL photons are emitted from the sample during ion-beam-induced excitation process of outer shell electrons of the target atoms and molecules. Thus, monochromatic IBIL images should contain information of the structure or chemical composition of the target that micro-PIXE analysis could not achieve. Several images were experimentally obtained from several sample of particulate aerosol or biological cell samples by using 3 MeV proton micro-beam. The IBIL images of the samples had successfully visualized with target size around 10 microns. Monochromatic IBIL imaging were also obtainable from various target samples by the developed IBIL analysis system for the realization of the proposed chemical-state imaging.
