IRAQI JOURNAL OF APPLIED PHYSICS Vol. 22, No. 3, July-September 2026, pp. 413-421 Influence of Precursor Concentration on Structural and Reger A. Ramadhan* Sabah M. Ahmed Morphological Properties of Eco- Friendly Synthesized Magnesium Oxide Nanoparticles Department of Physics, College of Science, This study presents an eco-friendly green synthesis of magnesium oxide nanoparticles University of Duhok, (MgO NPs) using Prunus persica leaf extract, investigating the critical role of precursor Duhok, Kurdistan Region, IRAQ concentration (0.15–0.4 M) in tuning their structural, morphological, and optical *Corresponding author Email: properties. XRD confirmed the formation of a pure cubic MgO phase, with crystallite size regrabdullrahman2017@gmail.com increasing from 10.83 nm to 36.14 nm as precursor concentration rose. SEM revealed that 0.3 M yielded well-defined, spherical nanoparticles (~87 nm) The 0.3 M precursor concentration is optimal because it balances nucleation and growth, allowing
