Abstract:
A yttrium silicate based phosphor with excellent luminescent efficiency at low voltages for utility in field emission devices (FEDs), and a method for synthesizing the phosphor. The yttrium silicate based phosphor contains Eu, Ce or Tb as an activator, phosphorus as a flux, and Zn as a sensitizer, based on a yttrium silicate phosphor, for example, Y3SiO5:Tb phosphor, and thus the luminance is improved.
