- CdCO3 thin films had grown onto glass by chemical bath deposition （CBD）, the temperature of the bath （Td） was at 20 °C. The samples were thermal annealed temperature （TAT） in air atmosphere at normal pressure for 2 h at different temperatures in the range of 300-400 °C, in order to perform the crystalline phase transformation from CdCO3？CdO, Scanning Electron Microscopy （SEM）, X-ray diffraction （XRD） and optical absorption （OA） measurements were carried out to characterized the films. The proportion of constitutive elements measured by means SEM for CdCO3 as-grown were： Cd = 12.8, C = 20.0, O = 67.2; TAT （CdCO3） = 400 °C： Cd = 49.8, O = 50.2, this results indicates good stoichiometric of samples. Patterns XRD show the layer with CdCO3 which has rhombohedral crystallineas-grown peaks at： 2？ = [23.4, 30.2, 36.4, 40.1, 43.8, 48.0, 49.5, 49.9, 58.2, 61.7, 62.9 and 65.5]. TAT （CdCO3） = 400 °C completely disappeared and only peaks of CdO are identified. All of the peaks in this pattern has pure cubic phase of CdO （
