The persistent MAl2O4:Eu2+, Dy3+ (M may be Ca or Ca+Ba or Ca+Mg) blue light emitting nanophosphors were prepared by rapid facile gel combustion technique. For the syntheses of present series of phosphors, urea was used as an organic fuel and boric acid was used as a flux in presence of air. Photoluminescence properties were studied by excitation and emission spectra. The phosphors showed blue luminescence (λmax= 454-458nm) under the excitation of UV source, attributed to 4f65d1→4f7 transitions of the Eu(II) ion. The effect on photoluminescence intensity and decay time was also studied for varying metal ions in different ratio (Ca or Ca+Ba or Ca+Mg). The existence of divalent europium ions in the synthesized lattices was confirmed by the X-ray photoelectron spectroscopy. The crystal phase and size of the prepared materials were analyzed with X-ray diffraction patterns. The surface morphology of phosphors was studied with scanning electron microscopy and transmission electron microscopy techniques revealed the average size of the prepared materials between the 30-50 nm. The prepared nanophosphors had bright optoelectronic properties that could be efficiently applied in various solid state white light emitting display devices.
