Measurement of the X-ray luminescence and spectral compatibility of the CdPO 3CI:Mn phosphor

The absolute efficiency, the spectral matching factor, the effective efficiency and the detective quantum efficiency of CdPO 3Cl:Mn phosphor were evaluated to test its suitability for use in medical or other type of radiation detectors. CdPO 3Cl:Mn was tested for 21– 275 mg/ cm 2 coating weights and...

Summary:The absolute efficiency, the spectral matching factor, the effective efficiency and the detective quantum efficiency of CdPO 3Cl:Mn phosphor were evaluated to test its suitability for use in medical or other type of radiation detectors. CdPO 3Cl:Mn was tested for 21– 275 mg/ cm 2 coating weights and for 50–250 kVp X-ray tube voltages. CdPO 3Cl:Mn was most efficient between 70 and 110 kVp and its emission spectrum extended from 450 to 650 nm, being compatible with modern optical detectors. Additionally, a theoretical model was used to fit experimental data and to estimate the intrinsic conversion efficiency (0.12) and the reciprocal diffusion length (27 cm 2/ g) .
