Novel composite nanomaterials with superior thermal and pressure stability for potential LED applications

A novel white-emitting [email protected]2O3 core/shell nanomaterials was synthesized by a green chemical method. The temperature and pressure dependence of the photoluminescence (PL) transition associated with the fundamental bandgap of [email protected]2O3 core/shell nanomaterials have been studied. The activation energy of [email protected]2O3 is 0.27 eV, which is higher than the commercial Y2O3: Eu 3+. The near-bandedge emission is found to...
