In order to meet the growing demand for new technologies, new materials with improved electrical, electronic, and electrochemical properties are needed. In the present work, the biosynthesis of zinc oxide nanoparticles was carried out with the aid of
Tilia
extract, varying the amount of extract used to obtain unique properties. The amounts of extract used were 1, 2, and 4% (volume ratio of water/weight of
Tilia
). The nanoparticles were characterized by FTIR, TEM, XRD, UV–Vis, and EIS. The analyses revealed that the nanoparticle composition includes organic material components from the
Tilia
extract. The average sizes shown by the nanoparticles were 41.8, 38.5, and 33.2 nm. XRD analyses determined that the nanoparticles have a hexagonal structure with a Wurtzite phase and crystallite sizes of 30.97 nm for 1%, 28.62 nm for 2%, and 14.52 nm for 4%. For the optical properties, the band gap values of the samples were 2.80, 2.64, and 2.47 eV for 1, 2, and 4%, respectively. Due to these characteristics, the obtained nanoparticles presented outstanding electrochemical properties that could benefit optoelectronic devices.
