Abstract

Li2CaSiO4:Eu2+ cyan phosphor screen for enlarging the color gamut of field emission display has been prepared and characterized. The luminance of Li2CaSiO4:Eu2+ phosphor film can reach as high as about 12000 cd/m2 under the conditions of Va = 7 kV and Ja = 2.8 mA/cm2. The cathodoluminescent spectrum, luminance, saturation current density and degradation property are compared with another cyan phosphor Mg2SnO4:Ti4+,Mn2+. It is found that Li2CaSiO4:Eu2+ phosphor exhibits narrower emission band, higher luminance, higher saturation current density, higher resistance to electron bombardment, higher thermal stability and conductivity as well as purer color. Thus, Li2CaSiO4:Eu2+ has great potential in application in field emission display as well as light emitting diode.
