Effect of flux content on thermoluminescence yield of BaS phosphors
BaS phosphors doped with impurities like Cu and Bi were prepared by using NaCl as flux. Thermoluminescence of these samples prepared with different quantities of flux has been studied by exciting them at room temperature with x-rays. The amount of flux for a good thermoluminescence yield has been estimated between 25 to 30% by weight depending upon the type of phosphor.
