Abstract

The current endeavor chronicles the synthesis of praseodymium-doped zinc oxide nanoparticles via the chemical precipitation method. SEM analysis examines the doping concentration role on the morphology of the nanoparticles. UV-Vis measurements indicate the optical band gap of the material ranges from 3.22 to 3.12 eV. The hole concentration and electron concentration are examined as a function of doping concentration. Diverse models are employed to ascertain the refractive index of the prepared nanoparticles. We also report the antibacterial activity of the nanoparticles against Gram-positive and Gram-negative bacteria, which cause septicemia. The prepared photocatalyst has excellent photocatalytic activity against methylene blue dye. The maximum degradation of 76% is observed and reported in this work when the doping concentration of Pr is 5%.
