The energy storage properties of Lu2O3:Tb,V sintered materials when exposed to X-rays were investigated for the first time using a number of thermoluminescent techniques. Thermoluminescence was generated exclusively by the Tb3+ ions, which served als

The persistent luminescence (PersL) dependence on the dopants and derived mechanism of trapping and de-trapping processes were investigated in Y3Al2Ga3O12 (YAGG) based nanophosphor, doped with Ce3+ and/or Cr3+. It is found that the presence of Cr3+ i

A series of energy storage phosphors, Lu2O3:Tb,M (M = Hf, Zr, Ti), were investigated by means of photo- and thermoluminescence techniques to compare the effect of the co-dopant from the same group of periodic table of elements on charge carriers trap
