Synthesis of Mg067Zn03Al2O4:0.03Dy and investigation of its optical properties

The morphological and visual properties of Magnesium Zinc Aluminate (Mg0.67Zn0.3 Al2O4) nanophosphor impured with Dysprosium (Dy3+) of 0.03 mol were reported in the present paper. Urea (NH2-CO-NH2) was used as fuel, Mg0.67Zn0.3 Al2O4(Pure)& Mg0.67Zn0.3 Al2O4 doped with 0.03 mol of Dysprosium (Dy3+) nanophosphors were synthesized through a solution combustion technique. The emergence of Mg1-xZnx Al2O4(Pure) & Mg1−x−yZnx Al2O4: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 MgZnAl2O4 nanocrystallites were investigated through X-ray diffraction (XRD) having Cu Kα [40 kV,15 mA X-ray] at λ = 1.541862°A,the stage rec- ognization and interposed stage emergence were established through the appearance of the heterojunctions peak at 2θ = 36.73◦ and Fourier Trans- form Infrared (FT-IR) Spectroscopy(PEService).An Optical energy gap(Eg) of 1.23 eV calculated by Tauc Plot Method confirmed that Mg1−x−yZnxAl2O4, may be semiconducting materials.The result proved that the MgZnAl2O4 with an average particle size of 28.34 nm and 21.99 nm for pure and impure nanophosphors are crystalline in nature.The nanophosphors size were calculated by Scherer’s equation.
