luminescence investigation of ce doped zno/cdwo4 nanocomposite

Novel luminous materials are always required in solid-state light-emitting diodes and displays applications.in this regard, the current study investigated the luminescence properties of cerium-doped zincoxide/cadmium tungstate (zno/cdwo4: ce) nanocomposite particles under proton, laser, and gamma-rayexcitations. the xrd results revealed the simultaneous existence of monoclinic cwo and hexagonal zno.doped nanocomposite particles under proton/laser irradiations displayed significant luminescence in theblue-green region compared with the pure nanocomposite. in addition, thermo-luminescence (tl) studyof the doped pellet showed a stronger glow peak at 350-400 °c. according to the tem, the dopednanoparticles had an average diameter of 70-150 nanometers. the existence of zn, o, cd, w, and ceelements in the composites was confirmed by the edx technique. the obtained results showed that theproduced zno/cwo: ce nanocomposite particles could be promising materials to be used in optoelectronicdevices.
