title: Optical Properties of Yellow EuSi2O2N2 Nanophosphor.
abstract: The EuSi2O2N2 nanophoshor was prepared by high-energy planetary mill. The nanophosphor with 100 nm in a mean size showed a broad yellow emission spectrum with the peak at 557 nm and the half width of 61 nm due to Eu2+ f-d transition. Its excitation spectrum was drastically decreased in shorter and longer wavelength sides. The fabricated white-light-emitting diode by a remote-phosphor structure exhibited the better color rendering index than that of the bulkphosphor, which is similar with that with YAG phosphor.
