Low temperature synthesis and characterization of nanocrystalline CdO film by using a solvothermal method without any additives

Cadmium oxide film is synthesized via solvothermal method which benefits from simple low temperaturetechnique. a uniform and crack free film of cdo is coated on a glass substrate. the synthesized film is annealedat 350°c for 1 hour in order to produce pure phase of cdo with good adherence. films are characterized by x-raydiffraction, scanning electron microscopy (sem), thermogravimetric (tga)- differential thermal (dta) analysis,fourier transform infrared (ft-ir) and photoluminesence (pl) spectroscopy. grain size of the annealed film isproved to be about 30-100 nm. band gap was also calculated using uv-visible spectroscopy.pacs: 68.55.–a, 68.55.jk, 81.07.–b, 61.46.–w
