Abstract
Gd doped ZnO nanoparticles with differing dopant concentration are synthesized by co-precipitation method and analysed for their structural, morphological and optical properties. XRD profiles confirmed that the synthesized material is nano-crystalline ZnO with well-crystalline and hexagonal wurtzite structure. FESEM images delineated hexagonal formed in ZnO nanoparticles. The assimilation band gap observed 463 cm−1 is credited to the ZnO extending vibrations and EDX affirms the synthesis of undoped and Gd doped ZnO nanoparticles. Optical properties of the nanoparticles were examined by photoluminescence study and it uncovered band edge emission for all synthesized materials with additional emissions in visible region because of the presence of opening and interstitial deformities. The antibacterial effectiveness of Gd doped ZnO nanoparticles were investigated against a Gram positive and Gram negative bacteria.
