Abstract
Dy2+x (x = 0.000, 0.015, 0.035, and 0.055 % molar concentration) doped strontium calcium aluminates based nanophosphor Sr0.85-xCa0.15Al12O19 was synthesized by combustion technique, utilizing urea as a fuel at an initial temperature of 550 °C. Phase recognition, morphological analysis, and elemental evaluation were accomplished using X-ray diffraction, Field emission scanning electron microscopy (FE-SEM), and EDS spectra. Spectroscopic photoluminescence techniques of the described phosphor maintained optical characteristics. The PL emission spectra revealed the characteristic Dy2+ emission peaks around 666 nm, which can be attributed to the 4F9/2 - 6H11/2 of ions transition. According to the CIE diagram, the optimal emission intensity for SrCaAl12O19:Dy2+0.055 were recorded in the red region. The phosphor described has practical uses as a refractory structural material, and it can be employed in a variety of technologies. We developed strontium aluminates phosphor with better characteristics using a 0.15 M calcium concentration.
