Nanoparticle formation for irradiances between 6.5 mW/cm(2) and 13.3 mW/cm(2) in the 330-550 nm wavelength range is investigated and the results are compared to those of the nanoparticles synthesized in the dark and under direct sunlight. Ultraviolet-visible spectroscopy, Fourier-transform infrared spectroscopy and proton nuclear magnetic resonance spectroscopy, along with particle size analysis and transmission electron microscopy are employed for the characterization of samples and extracts. Irradiance is found to have profound influence on the reduction rates. However, size and spherical shape of the nanoparticles are persistent, irrespective of irradiance and wavelength. Irradiance is discussed to influence the particle formation and aggregation rates through the formation of free radicals in the fig extract.eninfo:eu-repo/semantics/closedAccessBiosynthesisFicus caricaIrradiationSilver nanoparticlesOptical-propertiesExtracellular biosynthesisBiological synthesisMetal nanoparticlesGold nanoparticlesAuAgPhotoreductionActinomyceteGrowthSpectroscopyAgglomerationBiochemistryBiosynthesisFree radicalsIrradiationNanoparticlesNuclear magnetic resonance spectroscopyParticle size analysisTransmission electron microscopyUltraviolet visible spectroscopyAggregation rateAqueous mixturesFicus caricaNanoparticle formationParticle formationsProton nuclear magnetic resonance spectroscopySilver nanoparticlesWavelength rangesSilverFicusGreen chemistry technologyLightMetal nanoparticlesParticle sizePlant extractsPlant leavesProton magnetic resonance spectroscopySilverSpectrophotometry, ultravioletSpectroscopy, fourier transform infraredTime factorsX-Ray diffractionArticle0003433377000212-s2.0-8490504622915316113525062061SpectroscopySilver Nanoparticles; Green Synthesis; BiofabricationMetal nanoparticlePlant extractSilverChemistryFicusGreen chemistryInfrared spectroscopyLightParticle sizePlant leafProceduresProton nuclear magnetic resonanceTimeUltrastructureUltraviolet spectrophotometryX ray diffraction
