Study on the Path Process of Gd and Mg Doped ZnO Nanostructures by the Sol-gel Method | Chapter 3 | Newest Updates in Physical Science Research Vol. 15

 Doping is one of the most effective ways to change the physical properties of ZnO to expand its applications. Zn1-xMxO nanopowders (M = Gd, Mg, and x = 0, 0.03) were produced by sol-gel technique and sintering at 600oC for 2 hours were reported. Thermal gravimetric analysis (TGA) was used to analyse the decomposition process of the dried gel system, and FT-IR spectroscopy was used to investigate nanopowders with different heating temperatures. Using X-ray diffraction, the crystal structure of the nanopowders after sintering at 600oC. (XRD). The weight loss regions on the TGA curves of the samples correlate to the removal of beginning materials, with no weight loss found in the temperature range of 300 to 800oC, which corresponds to the phase-crystallization stage. The stretching frequency of ZnO is 669 cm-1, and Gd/Mg doped ZnO is 668 cm-1, 666 cm-1 in the FT-IR spectra. The crystal structure of samples revealed by XRD tests to be single phase ZnO crystalline with a hexagonal wurtzite structure (space group P63mc)
