A scrutiny of antibacterial activity of pure and iodine doped ZnO thin films synthesized by mSILAR method
Thomas D.; Abraham J.; Sadasivuni K.K. ( American Institute of Physics Inc. , 2019 , Conference Paper)Iodine doped zinc oxide (I-ZnO) thin films were synthesized by microwave assisted successive ionic layer adsorption (mSILAR) method. The structural characteristics of pure ZnO and I-ZnO thin films were carried out by powder ... -
