中文摘要	msi2o2-delta n2+2/3 delta:eu2+ (m = sr, ba) phosphors were prepared through a two-step solid state reaction. xrd results reveal that the samples are nitrogen-rich phase. the photoluminescence results show that the msi2o2-delta n2+2/3 delta:eu (m = sr, ba) phosphors can be excited by uv and blue light. the critical concentrations of eu2+ are 5 mol% and 4 mol% for msi2o2-delta n2+2/3 delta:eu (m = sr, ba), respectively. with an increase of the eu2+-concentration, the emission color of srsi2o2-delta n2+2/3 delta:eu can be tuned from green to yellow. under the excitation of low voltage electron beams (1-3 kv), the msi2o2-delta n2+2/3 delta:eu (m = sr, ba) phosphors exhibit green and cyan emission, respectively. the emission intensity increases with the increasing of accelerating voltage and filament current. due to the excellent stability, good cie chromaticity and high color purity, msi2o2-delta n2+2/3 delta:eu (m = sr, ba) phosphors may have potential application in the field emission displays. crown copyright (c) 2011 published by elsevier b.v. all rights reserved.
