Silver nanoparticles were prepared by the reduction of silver salt (silver nitrate AgNO 3) solution using three different methods. The main differences between these methods is by belong to the reducing agent. It is found that the prepared silver nanoparticle was pure and stable for long time. UV-VIS spectrometry indicated formation of spherical silver nano particles. The surface plasmon resonance peaks in absorption spectra for silver colloidal solution showed that the absorption maximum range was at 380-420 nm. The structures are confirmed by X-ray diffraction (XRD) and the crystallite size was determined from X-ray line broadening using the Scherrer's equation and it was about 32 nm.AFM measurements show that silver nano particles have the average diameter of 69.39 nm and 81.91 nm. ‫اﻟﻔﻀﺔاﻟﻨﺎﻧﻮﯾﺔ‬ ‫ﻟﺪﻗﺎﺋﻖ‬ ‫اﻟﻄﯿﻔﯿﮫ‬ ‫اﻟﺪراﺳﺔ‬ ‫اﻟ‬ ‫اﻟﻜﯿﻤﯿﺎﺋﯿﺔ‬ ‫ﺑﺎﻟﻄﺮﯾﻘﺔ‬ ‫ﻤﺤﻀﺮه‬ ‫اﻟﺨﻼﺻﮫ‬ ‫ﺗﺤﻀﯿﺮ‬ ‫ﺗ++ﻢ‬ ++‫دﻗﺎﺋﻘﺎﻟﻔﻀ‬ ‫ﮫ‬ ‫ﺑﺎ‬ ‫++ﺔ‬ +‫اﻟﻨﺎﻧﻮﯾ‬ ‫++ﺔ‬ +‫ﺛﻼﺛ‬ ‫ﺳ++ﺘﺨﺪام‬ ‫ط++ﺮ‬ ‫++ﺎﺧﺘﺰال‬ +‫ﺑ‬ ‫وذﻟ++ﻚ‬ ‫++ﮫ‬ +‫ﻣﺨﺘﻠﻔ‬ ‫ق‬ ‫++ﺔ‬ +‫اﻟﻔﻀ‬ ‫ﻧﺘ++ﺮات‬) (AgNO 3 . ‫ان‬ ‫+ﯿﻦ‬ +‫ﺑ‬ ‫+ﻲ‬ +‫اﻟﺮﺋﯿﺴ‬ ‫+ﺘﻼف‬ +‫اﻻﺧ‬ ‫+ﺬه‬ +‫ھ‬ ‫+ﺮق‬ +‫اﻟﻄ‬ ‫اﻟ‬ ‫+ﺘﺨﺪام‬ +‫اﺳ‬ ‫+ﻮ‬ +‫ھ‬ ‫+ﻞ‬ +‫ﻌﺎﻣ‬ ‫اﻟﻤ‬ ‫+ﺰل‬ +‫ﺨﺘ‬ . ‫اﻟﻨﺎﻧﻮ‬ ‫+ﮫ‬ +‫اﻟﻔﻀ‬ ‫+ﺎﺋﻖ‬ +‫دﻗ‬ ‫+ﮫ‬ +‫ﯾ‬ ‫+ﺪ‬ +‫وﺟ‬ ‫+ﺮة‬ +‫اﻟﻤﺤﻀ‬ ‫ت‬ ‫+ﮫ‬ +‫ﻧﻘﯿ‬ ‫اﻟﻄﻮﯾﻞ‬ ‫ﻟﻮﻗﺖ‬ ‫ّة‬ ‫وﻣﺴﺘﻘﺮ‬ . ‫اﻟﻜﺮوﯾﮫ‬ ‫اﻟﻔﻀﯿﺔ‬ ‫اﻟﻨﺎﻧﻮﯾﺔ‬ ‫اﻟﺪﻗﺎﺋﻖ‬ ‫ﺗﺸﻜﯿﻞ‬ ‫اﺷﺎرإﻟﻰ‬ ‫اﻟﻄﯿﻒ‬ ‫ﻗﯿﺎس‬ ‫ﺟﮭﺎز‬ . ‫طﯿ+ﻒ‬ ‫ﻗﻤﻢ‬ ‫+ﻲ‬ ّ ‫اﻟﻔﻀ‬ ‫ﻟﻠﻤﺤﻠ+ﻮل‬ ‫اﻻﻣﺘﺼ+ﺎص‬ ‫ﻣﺪى‬ ‫ﻓﻲ‬ ‫ﻛﺎن‬ ‫اﻷﻋﻈﻢ‬ ‫اﻹﻣﺘﺼﺎص‬ ّ‫ﺑﺄن‬ ‫اظﮭﺮت‬) nm420 -380 .(‫ﻗﯿﺎس‬ ‫ﺑﻮﺳﻄﺔ‬ ‫ﺪة‬ ّ ‫ﻣﺆﻛ‬ ‫اﻟﺒﻠﻮري‬ ‫واﻟﺤﺠﻢ‬ ‫اﻟﻨﺎﻧﻮﯾﮫ‬ ‫اﻟﻔﻀﮫ‬ ‫ﻟﺪﻗﺎﺋﻖ‬ ‫اﻟﺘﺮﻛﯿﺐ‬ ‫ﺣﯿﻮد‬ ‫اﻟﺴﯿﻨﯿﺔ‬ ‫اﻻﺷﻌﺔ‬) XRD (‫ﺑﺈﺳ+ﺘﻌﻤﺎل‬ ‫و‬ ‫ﻣﻌﺎدﻟﺔ‬ Scherrer's ‫ﺣﻮاﻟﻲ‬ ‫ﻛﺎن‬ 32nm . INTRODUCTION* olloidal particles are increasingly receiving attention as important starting points for the generation of micro and nano structures [1]. These particles are under active research because they posses interesting physical properties differing considerably from that of the bulk phase. It comes from small sizes and high surface/volume ratio [2].Silver nano particles have received considerable attention due to their attractive physical and chemical properties. Metallic silver colloids were first prepared more than a century ago. Ag nanoparticles can be synthesized using various methods: chemical, electrochemical [3], γ-radiation [4] photochemical [5], laser ablation
