In this research, we are studying structural and optical properties of film (PVA doped with CuO and FeCl 3).The(CuO)with concentration (7%), and (FeCl 3) with different concentrations of FeCl 3 (3, 7, and 9) %,preparing by casting method with thickness (25±5) µm, the structure characterized by using (XRD).The investigation of (XRD). indicates that the pure (PVA) and doping films are polycrystalline structure. The results of the measuring size, micro grain strain, dislocation density and number

The absorbance and transmittance spectra have been recorded in the wavelength range (200-1100) nm inorder to studying the optical properties. The optical band gap of (PVA) decreases with increasing concentration of FeCl 3 from(4.3-1.6) eV, and extinction coefficient, refraction index, the optical conductivity are varies with increasing concentration. ‫ﺑﺎوﻛﺴﯿﺪ‬ ‫اﻟﻤﺸﻮﺑﺔ‬ ‫اﻟﻜﺤﻮل‬ ‫ﻓﯿﻨﺎل‬ ‫ﺑﻮﻟﯿﻤﺮ‬ ‫ﻻﻏﺸﯿﺔ‬ ‫واﻟﺒﺼﺮﯾﺔ‬ ‫اﻟﺘﺮﻛﯿﺒﯿﺔ‬ ‫اﻟﺨﻮاص‬ ‫دراﺳﺔ‬ ‫و‬ ‫اﻟﻨﺤﺎس‬ ‫ﻛﻠﻮرﯾﺪ‬ ‫اﻟﺤﺪﯾﺪ‬ :‫اﻟﺨﻼﺻﺔ‬ ‫اﻟﻤﺸﻮﺑﺔ‬ ‫اﻟﻜﺤﻮل‬ ‫ﻓﯿﻨﺎل‬ ‫ﺑﻮﻟﯿﻤﺮ‬ ‫ﻻﻏﺸﯿﺔ‬ ‫واﻟﺒﺼﺮﯾﺔ‬ ‫اﻟﺘﺮﻛﯿﺒﯿﺔ‬ ‫اﻟﺨﻮاص‬ ‫دراﺳﺔ‬ ‫ﺗﻢ‬ ‫اﻟﺒﺤﺚ‬ ‫ھﺬا‬ ‫ﻓﻲ‬ ‫ﺑﻨﺴﺒﺔ‬ ‫اﻟﻨﺤﺎس‬ ‫ﻛﻠﻮﯾﺪ‬ (‫اﻟﺤﺪﯾﺪ‬ ‫وﻛﻠﻮرﯾﺪ‬ ‫اﻟﻨﺤﺎس‬ ‫)ﺑﺎوﻛﺴﯿﺪ‬ (7%) ‫ﻣﺨﺘﻠﻔﺔ‬ ‫ﺑﻨﺴﺐ‬ ‫اﻟﺤﺪﯾﺪ‬ ‫وﻛﻠﻮرﯾﺪ‬ (3, 7, and 9) % ‫وﺑﺴﻤﻚ‬ ‫اﻟﺼﺐ‬ ‫ﺑﻄﺮﯾﻘﺔ‬ ‫اﻟﻤﺤﻀﺮة‬ ,(25±5) µm ‫اﻟﺴﯿﻨ‬ ‫اﻻﺷﻌﺔ‬ ‫ﺣﯿﻮد‬ ‫ﺗﻘﻨﯿﺔ‬ ‫وﺑﺎﺳﺘﺨﺪام‬ ‫ﯿﺔ‬. ‫وﻛﺜﺎﻓﺔ‬ ‫اﻟﺤﺒﯿﺒﻲ‬ ‫اﻟﺤﺠﻢ‬ ‫ﻣﻦ‬ ‫ﻛﻞ‬ ‫ﺣﺴﺎب‬ ‫وﺗﻢ‬ ‫اﻟﺘﺒﻠﻮر‬ ‫ﻣﺘﻌﺪد‬ ‫ﺗﺮﻛﯿﺐ‬ ‫ذات‬ ‫اﻟﻤﺸﻮﺑﺔ‬ ‫اﻟﻨﻘﯿﺔ‬ ‫اﻻﻏﺸﯿﺔ‬ ‫ان‬ ‫وﺟﺪ‬ ‫اﻻﻧ‬ ‫ﺨ‬ ‫أن‬ ‫وﺟﺪ‬ ‫وﻗﺪ‬ ‫ﻧﻤﻮذج‬ ‫ﻟﻜﻞ‬ ‫اﻟﻄﺒﻘﺎت‬ ‫وﻋﺪد‬ ‫اﻟﺒﻠﻮرة‬ ‫وﺗﺸﻮه‬ ‫ﻼﻋﺎت‬ ‫اﻟﺤﺒﯿﺒﻲ‬ ‫اﻟﺤﺠﻢ‬ ‫ﻣﻦ‬ ‫ﯾﺰداد‬ (3.676-11.57)nm ‫ﺿﻤﻦ‬ ‫ﺳﺠﻞ‬ ‫واﻟﻨﻔﺎذﯾﺔ‬ ‫اﻻﻣﺘﺼﺎﺻﯿﺔ‬ ‫طﯿﻒ‬ ‫اﻣﺎ‬. ‫ﻟﻠﺸﻮاﺋﺐ‬ ‫اﻟﺘﺮﻛﯿﺰ‬ ‫زﯾﺎدة‬ ‫ﻣﻊ‬ ‫اﻟﻄﻮل‬ ‫ﻣﺪى‬ ‫اﻟﻤﻮﺟﻲ‬ (200-1100)nm ‫ﻣﻦ‬ ‫اﻟﺤﺪﯾﺪ‬ ‫ﻛﻠﻮرﯾﺪ‬ ‫ﻧﺴﺒﺔ‬ ‫ﺑﺰﯾﺎدة‬ ‫ﺗﻘﻞ‬ ‫اﻟﻄﺎﻗﺔ‬ ‫ﻓﺠﻮة‬ ‫ان‬ ‫وﺟﺪ‬ ‫وﻗﺪ‬ (4.3-1.6)eV ‫اﻟﺘﺸﻮﯾﺐ‬ ‫ﻧﺴﺒﺔ‬ ‫زﯾﺎدة‬ ‫ﺑﻌﺪ‬ ‫ﺗﺘﻐﯿﺮ‬ ‫اﻟﺒﺼﺮﯾﺔ‬ ‫واﻟﺘﻮﺻﯿﻠﯿﺔ‬ ‫اﻻﻧﻜﺴﺎر‬ ‫وﻣﻌﺎﻣﻞ‬ ‫اﻟﺨﻤﻮد‬ ‫ﻣﻌﺎﻣﻞ‬ ‫اﻣﺎ‬ .
