This paper reports the synthesis and the characterization of 1D Zinc titanate nanobelts of different molar ratios Zn/Ti = 0.26-0.40-0.80 (Zn(CH3COO)2/TTIP) prepared by electrospinning. The samples were annealed at 600°C and 900°C temperatures in air for 5 hr. The as-spun and annealed (Zn(CH3COO)2/ TTIP)/PVP composite nanobelts were characterized by scanning electron microscopy (SEM), Energydispersive X-ray spectroscopy analysis (EDX), X-ray diffraction (XRD), Raman spectroscopy and photoluminescence (PL). The results in this paper demonstrate that heat treatment has an influence on the process of crystallization. According to the X-ray diffraction, the formation of ZnTiO3 rhombohedral phase. Raman spectroscopy results confirm the formation of ZnTiO3 phase. They are in good agreement with the X-ray diffraction. Photoluminescence reveals that high quantity of Titanium makes shift from emitted bands to greater wavelengths (visible region). However, high temperature causes a shift from emission bands to greater wavelengths and regeneration of other bands.
