New red SrTiO₃:Pr³⁺ phosphor for the field emission displays application was
prepared using the sol-gel method. The reaction between starting materials SrCl₂, Ti-(Oi-C₃H₇)₄
and PrCl₃ resulted in a mix of compounds transformed to single-phase
SrTiO₃:Pr after its annealing in air. Optimal technological conditions for preparation of
efficiently radiating SrTiO₃:Pr³⁺ phosphors were found. Both photoluminescence and
cathodoluminescence spectra showed the high intensity red peaks at the wavelength
λmax = 617 nm. The high luminance of 300 cd/m²
was obtained at the anode voltage of
10 kV.
