“…In the 2000s, the OSL properties of cesium mixed halide crystals including Eu-doped Cs(Cl, Br) and Cs(Br, I) were developed, 48,50,79) and N.G. Subramaniam et al reported that the OSL emission and stimulation spectra of Eu-doped Cs(Cl, Br) crystals can be controlled by the ratio of anions.…”

Storage phosphor materials have a function to record the incident radiation dose, and they are often used for personal dose monitoring applications and imaging plates (IPs). Conventionally, the storage phosphors for IPs are mainly used in the form of powders and needle crystals while IPs using translucent ceramics have recently attracted much attention. In this paper, we review the recent studies of translucent ceramic storage phosphors for IPs in addition to conventional storage phosphors.

“…The behavior of the A-band absorption and luminescence, strongly influenced by the local symmetry around the impurity, temperature, concentration of the activator, and so on, has been studied thoroughly [4]. Recently [5][6][7][8][9][10]. However, optical studies on Tl + doped mixed alkali halides are still meager.…”

The optical absorption behavior of Tl + doped Rb(Br 1-x I x ) mixed crystals (with x = 0.00, 0.05, and 0.10) grown under vacuum by slow cooling from the melt has been studied. Absorption spectra of the mixed crystals recorded at room temperature showed that the characteristic A-absorption band of Tl + ions in the Rb(Br 1-x I x ) system (0.1 mol. %) with x = 0.00 (i.e., RbBr:Tl + ) broadened with the iodine content towards the low energy side. Changes in the absorption spectra of the mixed crystals are due to creation of some complex centers involving Tl + , Br -, and I − ions with energy levels inside the band gap while forming the mixed crystal. The absorption spectra of gamma-irradiated mixed crystals showed the F-band, which shifted towards the low energy side due to the existence of iodine ions in the mixed crystals.
