For X-ray irradiated fluoride-phosphate (FP) glasses with different phosphate content (from 0 to 20 mol%), a number of different radiation-induced defect centres (DC) were detected, which can be subdivided into three groups: phosphate, oxygen and fluorine related DC. The phosphate and oxygen related defects are paramagnetic, their optical absorption were established by means of band separation and correlation to EPR signals. The non-paramagnetic fluorine-related colour centres (FD centres) were found for FP glasses with lower (
