Abstract. New red SrTiO 3 :Pr 3+ phosphor for the field emission displays application was prepared using the sol-gel method. The reaction between starting materials SrCl 2 , Ti-(O- i-C 3 H 7 ) 4 and PrCl 3 resulted in a mix of compounds transformed to single-phase SrTiO 3 :Pr after its annealing in air. Optimal technological conditions for preparation of efficiently radiating SrTiO 3 :Pr 3+ phosphors were found. Both photoluminescence and cathodoluminescence spectra showed the high intensity red peaks at the wavelength  max = 617 nm. The high luminance of 300 cd/m 2 was obtained at the anode voltage of 10 kV.

Keywords: phosphor, SrTiO 3 :Pr, photoluminescence, cathodoluminescence, field emission displays, sol-gel method.
