I. Kandarakis et al., Measurement of the X-ray luminescence and spectral compatibility of the CdPO3Cl : Mn phosphor, RADIAT MEAS, 33(2), 2001, pp. 217-224
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). (C) 2001
