Abstract The solution-combustion synthesis (SCS) method was used to prepare silver nanoparticles using glycine and citric acid as fuels. The different combination of fuel to oxidant ratio was used to prepare Ag nanoparticles and its effect on optical spectra, structure and the morphology explored. The purposed method is rapid, effective, cheap and convenient. Silver nanoparticles with different sizes and shapes were synthesized depending upon the different oxidant/fuel ratios. The nanoparticles were characterized using transmission electron microscopy, X-ray diffraction and ultravioletvisible absorption spectroscopy. Histograms were drawn to compare the mean particle size of synthesized nanoparticles. It was found that citric acid was better fuel as compared to glycine as it results in the more spherical symmetrical nanoparticles, which are supported by various characteristic studies.

Introduction
Novel metal nanoparticle synthesis has received considerable attention in recent years as a result of their optical, electronic, magnetic and chemical properties and their potential applications in subsequent technology development (Chrystel et al. 2003). Silver nanoparticles can be used in areas such as integrate circuit (Kotthaus et al. 1997), cell electrode (Klaus et al. 2001), antimicrobial deodorant bre (Zhang and Wang 2003), catalysis (Claus and Hofmeister 1999), chemical analysis (Compagnini et al. 1997) and surface-enhanced Raman spectroscopy (Shirtcliffe et al. 1999; Bright et al. 1998). It has been demonstrated that, in the case of noble-metal nanocrystals, the electromagnetic, optical and catalytic properties are highly inuenced by shape and size (Liz-Marzan 2004; Mulvaney 1996; Burda et al. 2005). This has driven the development of synthesis routes that allow a better control of morphology and size. In most of the related studies reported previously (Bright et al. 1998; Sosa et al. 2003; Jiang et al. 2004; Wang et al. 2005; Kim et al. 2009; Liang et al. 2007), characteristic surface plasmon resonance of silver nanoparticles and nanowires have always been given the maximum importance because of the fact that it has been the rst
