摘要：

Until recently, it was difficult to measure properties of individual fluor grains. The development of an accelerator-based nuclear microprobe, as is currently available at the Louisiana Accelerator Center, has made this type of research possible. Using ion beams as small as 1 x 1 pin (horizontal x vertical extent), it is now possible to measure properties of individual fluor grains. Starting in 2000, a research program was initiated to determine the microscopic fluorescence properties for selected rare earth compounds, like Y2O2S : Eu. Particle-induced X-ray emission (PIXE) was used to characterize individual fluor grains. Individual Y2O2S : Eu grains are clearly visible in the analysis and are less than 10 mum in extent.
