GdCaAl3O7:Eu red nano-phosphors were synthesized by solution combustion using urea as fuel. Fourier-transform infrared, X-ray diffraction, scanning electron microscope, transmission electron microscope and photoluminescence spectrophotometer were used to characterize the obtained samples. XRD patterns revealed that GdCaAl3O7:Eu pure phase was formed by combustion of metal nitrate solution in th...
