Abstract:
This invention provides novel cadmium tungstate scintillator materials that show improved radiation hardness. In particular, it was discovered that doping of cadmium tungstate (CdWO4) with trivalent metal ions or monovalent metal ions is particularly effective in improving radiation hardness of the scintillator material.
Abstract:
Novel phosphor systems are disclosed having the formula A2SiO4:Eu2+D, where A is at least one of a divalent metal selected from the group consisting of Sr, Ca, Ba, Mg, Zn, and Cd; and D is a dopant selected from the group consisting of F, Cl, Br, I, S and N. In one embodiment, the novel phosphor has the formula (Sr1-x-yBaxMy)2SiO4: Eu2+F (where M is one of Ca, Mg, Zn, or Cd in an amount ranging from 0
