초록

Y2SiO5 Powder based on silicon and yttrium is well known as powder phosphors due to their excellent sustainability and efficiency. A new electroluminescence device was fabricated with Y2SiO5:Eu3+ powder phosphors though a simple screen printing method. The powder-dispersed electroluminescence device consisted of the Y2SiO5:Eu3+ powder-dispersed phosphor layer and BaTiO3-dispersed dielectric layer. The annealing temperature of the phosphor for the best powder electroluminescence performance was optimized to high temperature in ambient atmosphere though a solid-state reaction. The Eu3+ concentration for the best device performance was also investigated and furthermore, the thermal dependence of the electroluminescence intensity was investigated at the operating voltage at 100℃, which is the Curie temperature of the BaTiO3 layer. And the intensity was exponentially increased with voltage and increased linearly with frequency.
