Abstract
Spatially resolved x-ray secondary electron photoemission spectra reve aled lateral changes in quantum efficiency and chemical composition of polycrystalline cesium iodide photodetectors. Such changes depend on the substrate (stainless steel or aluminum). These results emphasize t he limitations of conventional, spatially integrated quantum efficienc y measurements, and shed new light on the chemical properties of inhom ogeneous polycrystalline cesium iodide.
