Effects of ${\hbox {Na}}^ + $ , ${\hbox {Mg}}^{2+} $ , ${\hbox {Ca}}^{2+} $ , ${\hbox {Sr}}^{2 +} $ and ${\hbox {Ba}}^{2 +} $ Doping on the Scintillation Properties of ${\hbox {CeBr}}_3$

The effects of Na+, Mg2 +, Ca2 +, Sr2 + and Ba2 + doping on the scintillation properties of CeBr3 are evaluated in this paper. Ca2 + and Sr2 + doped CeBr3 show different scintillation properties as compared to undoped CeBr3, i.e. an additional perturbed Ce3 + site with emission maxima red-shifted by 30 nm compared to unperturbed Ce3 + sites as evidenced by X-ray excited emission and photoluminesce...
