Hydrothermal synthesis of self-emitting Y(V,P)O4 nanophosphors for fabrication of transparent blue-emitting display device

摘要: Abstract Self-emiting Y(Vx,P1−x)O4 blue nanophosphors with various compositons (x=0.1–0.9) were synthesized by a facile hydrothermal route and subsequently annealed at different temperatures of 800–1100 °C for 2 h. A higher content vanadate in Y(V,P)O4 resulted larger particle growth upon annealing. The luminescence under vacuum ultraviolet excitation increased an increasing phosphate content. Considering the size luminescence, Y(V0.1,P0.9)O4 800, 1000, 1100 °C used formation transparent emissive layer. Nanophosphor layer was uniformly deposited on glass substrate screen-printing. ∼0.9 μm thick nanophosphor that prepared 1000 °C-annealed showed high visible transmittance value 78%. Transparent blue-emitting test panel plasma display simply fabricated using layer/glass as rear combining it front current panel, their discharge luminance properties discussed.
