Abstract: • KCl:Mn and KCl:Ce TL phosphors were synthesized by co-precipitation method for the first time. • UVC dosimetry properties of the produced microcrystalline were studied. • It showed that the above TL phosphors can be used for UVC dosimetry. • Different TL structure under gamma irradiation makes it possible to identify UVC component in mixed radiation field. Potassium chloride microcrystalline doped with Mn and Ce was successfully synthesized for the first time by the co-precipitation method and its thermoluminescence (TL) UVC dosimetry properties were investigated. The highest TL sensitivity was achieved at 0.3 and 0.5 mol% of Mn and Ce impurities respectively. The optimum annealing regime was found at 673 K for 15 min. The TL response is linear for illumination with UVC lamp up to 500 s. The optical band gap of 4.16 and 4.34 eV was obtained accordingly for the synthesized Mn and Ce doped KCl phosphor using the absorption spectrum. T m -T stop and computerized glow curve deconvolution procedures were used to identify the component TL glow peaks and kinetic parameters of the produced phosphor. Desired dosimetric features, besides the simple glow curve structure and separated glow peaks of the synthesized phosphors, presents them as good candidates for UVC dosimetry. [ABSTRACT FROM AUTHOR]
