Structural and optical studies on flowerlike strontium doped zinc oxide synthesized by hydrothermal method

Strontium-doped Zinc Oxide (Zn1−xSrxO with x = 0.01, 0.02, 0.03 and 0.04) has been successfully synthesised by coprecipitation assisted hydrothermal method. The crystallite size was calculated to be within the range of 14 to 20 nm. An increase in bond length on strontium doping was seen conforming successful Sr inclusion in the ZnO matrix. Strain analysis revealed that composition x = 0.04 had maximum strain since it possessed the least crystallite size. Maximum texturization has been seen in the case of x = 0.01 which can also be observed from the FE-SEM image. Morphologies such as nanobelts, rods and flowers were commonly observed. A variation of morphologies from nanobelts to nanoflowers were seen as the strontium concentration increased. The absorption studies revealed broad absorption in the UV region with a bandgap ranging between 3.17 to 3.22 eV. In addition to the absorption in UV region, the doped samples exhibited absorption in the visible region which could open doors for their potential application in photodegradation of dye over both UV and Visible spectrum. FTIR spectroscopy further confirmed the formation of ZnO.
