Abstract:
Zinc and Magnesium doped Ferric Oxide nanoparticles were synthesized by Sol - gel assisted technique from the chlorides of Iron (III) and Zinc (II) and Magnesium (II). Initially 0.2 mol of Aqueous FeCl3 was taken, added with acetic acid and continuously Stirred at 300 RPM. Later NaOH solution is added to the above prepared solution till it reaches PH = 7. Then solution heated with magnetic heater at 800 C for one hour, observed gel like solution washed, filtered and dried. Given Molar Percentage of Zinc Chloride (0.005M, 0.01M, 0.015M) and Magnesium Chloride (0.005M, 0.01M, 0.015M) added for Doping to Iron Chloride at PH = 7 of the solution and stirred for 10 minutes. The prepared solution is placed on magnetic stirrer with heater at 800 C for one hour, observed gel like solution washed, filtered and dried. The filtered and dried powder was then calcinated at 4500 C for 1 hour. The synthesized nanoparticles were characterized for determining the structure of material by X-ray diffraction, size and morphology by Scanning Electron Microscopy, Band Gap by UV-VIS spectroscopy, Modes of Vibration by Raman Spectroscopy. SEM analysis results revealed that the formation of Iron Oxide as sponge like or porous shapes visible as cotton balls and every 200nm size particles are combination of two or more particles of less than 100nm and grouped as single one. The doaping of Zinc and Magnesium increased the reflective nature and changed the shape and size of particle as random rod like particle morphology. The change in morphology was observed with addition of Zinc and Magnesium dopant, heating environment with the Na+ and OH- and Acetic acid are combinedly acts for a morphology change and self-assembling. UV-VIS spectroscopy shows the drastic increase in band gap due to doping of Zinc and Magnesium in Ferric Oxide matrix.
