Abstract
The absolute efficiency, the spectral matching factor, the effective effici ency and the detective quantum efficiency of CdPO3Cl:Mn phosphor were evalu ated to test its suitability for use in medical or other type of radiation detectors. CdPO3Cl:Mn was tested for 21-275 mg/cm(2) coating weights and fo r 50-250 kVp X-ray tube voltages. CdPO3Cl:Mn was most efficient between 70 and 110 kVp and its emission spectrum extended from 450 to 650 nm, being co mpatible with modem optical detectors. Additionally, a theoretical model wa s used to fit experimental data and to estimate the intrinsic conversion ef ficiency (0.12) and the reciprocal diffusion length (27 cm(2)/g).
