Abstract

Red-emitting phosphor powders of SrIn204 activated with Eu3+ ions were synthesized by a high pressure assisted combustion method. X-ray diffraction analysis of the crystalline properties of these powders revealed single phase SrIn2O4 for Eu concentrations up to 4 atomic % of Eu. The photo and cathodoluminescence emission spectra of SrIn 204: Eu3+ powder shows bright red emission mainly caused by the 5D07F2 intra-shell transition of Eu3+. Furthermore, photoluminescence excitation (PLE) spectroscopy revealed that an efficient energy transfer from the SrIn2O4 host lattice onto the Eu ions is accomplished in addition to the excitation band peaked at λ = 396 nm that directly excites the Eu ions, making this material an excellent candidate for applications in solid state white-emitting lamps.
