摘要： This invention relates to a halide-containing stimulable phosphor having improved moisture resistance and luminance, and a process for producing the same. The halide-containing stimulable phosphor is characterized in that, among elements constituting the outermost surface and inside of the phosphor, there is a difference in composition ratio of a halogen element between the outermost surface and the inside of the phosphor. A radiation image conversion panel, which has been improved, for example, in moisture resistance, luminance and image quality by using the phosphor, and a process for producing the same are also provided.
