Characteristics
Its luminescence spectrum is the typical Eu
390 nm in lattices of the BaFBr-type. The top in the luminescence spectrum is
shifted slightly to longer wavelengths due to the incorporation of iodide.
The stimulation spectrum is much broader than that of pure BaFBr and is shifted
to longer wavelengths. This shift is caused in the first place by the partial
replacement of Ba by Sr, and in the second place by the incorporation of iodide.
Thanks to the red-shift of the stimulation spectrum, maximum stimulability is
assured at 633 nm, the wavelength of the stimulating laser.
The Agfa phosphor has excellent dark decay characteristics. Two hours after
exposure, approximately 80% of the energy stored upon exposure is still
available. The image retention is greater than 50% up to 24 hours after irradiation.
