Abstract
- A reddish-orange-emitting SnO<subscript>2</subscript>:Eu<superscript>3+</superscript> phosphor for field emission displays ( FEDs) was successfully synthesized via a homogeneous precipitation route using urea as a precipitant. The influences of the dopant concentration of Eu<superscript>3+</superscript> and calcination temperature on optical properties were investigated. The low-voltage field emission properties of the FED device prepared using the synthesized SnO<subscript>2</subscript>:Eu<superscript>3+</superscript> phosphors were reported. Under the UV light, SnO<subscript>2</subscript>:Eu<superscript>3+</superscript> phosphors display the strong orange-red emission peaked at 587, 591, and 597 nm due to the <superscript>5</superscript> D<subscript>0</subscript>→<superscript>7</superscript> F<subscript>1</subscript> magnetic dipole transition of Eu<superscript>3+</superscript>. The phosphor doped with 1.0 mol% Eu<superscript>3+</superscript> possesses the highest photoluminescent ( PL) intensity. Under the low-voltage excitation of 300 V, the fabricated FED device exhibits the bright orange-red emission, high-voltage brightness saturation, and high color purity, which has a potential application in low-voltage full color FEDs.
