Calcination Process Effect on Phase Formation in Nano-Sized Zn0.9Mn0.1O Particles

This paper reports the effects of calcination process on the structural and mid-infrared optical properties of Zn0.9Mn0.1O nanopowders synthesized by the sol gel technique. The particle size was determined about 35 nm. X-ray diffraction analysis indicated that mono-phase wurtzite structure was exhibited in samples calcinated at low temperatures. Appearance of secondary phase was well clarified that tuning the percentage of these phases can be possible by manipulating the calcination temperatures. The characterization was completed by studying the mid infrared transmittance spectra obtained by Fourier transform infrared (FTIR) spectroscopy.
