Abstrakt: In this present work, it is envisaged to enhance seed germination using Mo doped WO3 nanoparticles. Mo as a micro nutrient plays a vital role in germination and growth in plant biology. The pristine and Mo doped WO3 (Mo:WO3) nanoparticles are synthesized using acid assisted precipitation technique. Both pristine and doped samples were characterized by XRD, SEM/EDS, FTIR, Raman, UV-DRS, PL and XPS spectral techniques. The XRD pattern corroborates the monoclinic phase of synthesised products. The SEM and EDS analysis shows effective doping of Mo into host lattices of WO3. The structural aspects were confirmed using FTIR and Raman spectral studies. The doping of Mo lead to a decrease in band gap energy assisted with increase in Urbach energy. The defect states in energy levels were studied using PL analysis and the chemical composition using XPS. The WO3 nanoparticles show robust antibacterial activities against the Pseudomonas aeruginosa and Xanthomonas oryzae pv bacterial strains. The seed germination properties on kodo millet seeds were evaluated showing a more pronounced effect for Mo doped than pristine WO3 nanoparticles. Hence this material can be used in such a way that the dopant Mo aids in seed germination while WO3 acts as a good antibacterial agent that retards plant growth. [ABSTRACT FROM AUTHOR]
