Abstract

Abstract: The morphological and visual properties of Zinc Magnesium Aluminate (Zn0.67 Mg0.3 Al2 O4 ) nanophosphor impured with Dysprosium (Dy 3+ ) of 0.03 mol were reported in the present paper. Urea (NH2 -CO-NH2 ) was used as fuel, Zn0.67 Mg0.3 Al2 O4 (Pure)& Zn0.67 Mg0.3 Al2 O4 doped with 0.03 mol of Dysprosium (Dy 3+ ) nanophosphors were synthesized through a solution combustion technique. The emergence of Zn1−x Mgx Al2 O4 (Pure) & Zn1−x−y Mgx Al2 O4 :YDy (x = 0.3 & Y = 0.03 mol) were confirmed by urea-nitrate incorporation through combustion synthesis manner at 550 °C. The morphological properties of Pure and impure ZnMgAl2 O4 nanocrystallites were investigated through X-ray diffraction (XRD) having Cu Kα [40 kV, 15 mA X-ray] at λ = 1.541862°A, the stage recognization and interposed stage emergence were established through the appearance of the heterojunctions peak at 2θ = 36.68 ◦ and Fourier Transform Infrared (FT-IR) Spectroscopy (PEService). An Optical energy gap(Eg) of 1.499 eV calculated by Tauc Plot Method confirmed that Zn1-x-y Mgx Al2 O4, may be semiconducting materials. The result proved that the Zn-MgAl2 O4 with an average particle size of 25.12 nm and 24.90 nm for pure and impure nanophosphors are crystalline in nature. The nanophosphors size were calculated by Scherer's equation.
