Abstract

A reddish-orange-emitting SnO2:Eu3+ 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 Eu3+ and calcination temperature on optical properties were investigated. The low-voltage field emission properties of the FED device prepared using the synthesized SnO2:Eu3+ phosphors were reported. Under the UV light, SnO2:Eu3+ phosphors display the strong orange–red emission peaked at 587, 591, and 597 nm due to the 5D07F1 magnetic dipole transition of Eu3+. The phosphor doped with 1.0 mol% Eu3+ 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.
