摘要：
An x-ray intensifying screen is disclosed containing magnesium tantalum niobium oxide as a phosphor in an ordered corundum crystalline form. The phosphor contains an activating amount of at least one of rubidium and cesium. The x-ray intensifying screens are useful in radiographic applications where it is important to reduce subject exposure to x-rays and also to create clear, sharp images.
