Structural and Optical Properties of Y1-xSrxCrO3 (x=0.0, 0.1)

In this paper, we have investigated the crystal structure and optical behaviour of Alkaline earth metal (Sr) doped Y1-xSrxCrO3 (x = 0.0, 0.1) ceramics. All the samples were synthesized successfully by ceramics solid-state reaction route. From X-ray diffraction (XRD) pattern of Y1-xSrxCrO3 (x = 0.0, 0.1) ceramics, we have found that there is no change in crystalline structure and it was indexed in the orthorhombic structure possessing space group Pbnm. FTIR spectra reveals the appearance of sharp peaks at 577, 485 and 416 cm(-1) for pristine YCrO3 and 566, 477 and 415 cm(-1) for Y1-xSrxCrO3. These modes attributes to Cr-O stretching, Y-O stretching and O-Cr-O deformation vibration, respectively. It has been observed that 10% doping of Srion reduces the band gap. The band gap of YCrO3 and Y1-xSrxCrO3 samples varies from 2.31 to 2.23 eV.
