Laser Pulses Effect on the Structural and Optical Properties of ZnO Nano particles Prepared by Laser Ablation in Water

Abstract

In this work ZnO Nps were fabricated by liquid phase pulse laser ablation (LP-PLA) technique. The experiments were carried out by using the radiation of the pulsed Nd:YAG laser operating at the 1060 nm wavelength, 9 ns pulse duration and 1 Hz repetition rate of Zn plate immersed in DIW water, the effect of laser pulses on the amount of ablated materials, structural, optical and morphology of ZnO Nps has been studied. The atomic absorption result shows that the amount of the ablated material is directly proportional to the number of laser pulses and the atomic force microscope show that the grain size of the obtained NPs are decrease with the number of laser pulses. The UV-Visible show a blue shift was recognized with a larger number of laser pulses while the photoluminescence result gives a blue shift with the decrease in number of laser pulses ‫ﻋﻠﻰ‬ ‫اﻟﻠﯿﺰر‬ ‫ﻧﺒﻀﺎت‬ ‫ﺗﺄﺛﯿﺮ‬ ‫و‬ ‫اﻟﺘﺮﻛﯿﺒﯿﺔ‬ ‫اﻟﺨﺼﺎﺋﺺ‬ ‫اﻟﺒﺼﺮﯾﺔ‬ ‫ﻟ‬ ‫ﺠﺴﯿﻤﺎت‬ ZnO ‫اﻟﻨﺎﻧﻮﯾﺔ‬ ‫ﺑﻮاﺳﻄﺔ‬ ‫اﻟﻤﺤﻀﺮة‬ ‫اﻹ‬ ‫زاﻟﺔ‬ ‫اﻟﻤﺎء‬ ‫ﻓﻲ‬ ‫اﻟﻠﯿﺰرﯾﺔ‬ ‫اﻟﺨﻼﺻﺔ‬ ‫اﻟﺒﺤﺚ‬ ‫ھﺬا‬ ‫ﻓﻲ‬ ‫ﺗﻤﺖ‬ ‫ﺗﺤﻀﯿﺮ‬ ‫ﺟﺴﯿﻤﺎت‬ ‫اﻟﺰﻧﻚ‬ ‫اوﻛﺴﯿﺪ‬ ‫اﻟﻨﺎﻧﻮﯾﺔ‬ ‫ﻓ�ﻲ‬ ‫ﺑﺎﻟﻠﯿﺰر‬ ‫اﻻﺳﺘﺌﺼﺎل‬ ‫ﺗﻘﻨﯿﺔ‬ ‫ﺑﺎﺳﺘﺨﺪام‬ ‫اﻟﺴﺎﺋﻞ‬ ‫اﻟﻮﺳﻂ‬. ‫اﻟﻨ�ﺪﻣﯿﻮم‬ ‫ﻟﯿ�ﺰر‬ ‫اﻟﺘﺸ�ﻌﯿﻊ‬ ‫ﺑﻮاﺳ�ﻄﺔ‬ ‫اﻟﺘﻘﻨﯿﺔ‬ ‫ﺗﻤﺖ‬-‫ﻣ�ﻮﺟﻲ‬ ‫ﺑﻄ�ﻮل‬ ‫ﯾﻌﻤ�ﻞ‬ ‫ﯾ�ﺎك‬ 1060 nm ‫واﻣ�ﺪ‬ ‫�ﺔ‬ �‫ﻧﺒﻀ‬ nsec 9 ‫�ﺔ‬ �‫اﻟﻨﺒﻀ‬ ‫�ﺮار‬ �‫ﺗﻜ‬ ‫�ﺪل‬ �‫وﻣﻌ‬ 1Hz ‫�ﻮر‬ �‫ﻣﻐﻤ‬ ‫�ﻚ‬ �‫اﻟﺰﻧ‬ ‫�ﺪن‬ �‫ﻟﻤﻌ‬ ‫�ﺮ‬ �‫اﻟﻤﻘﻄ‬ ‫�ﺎء‬ �‫ﺑﺎﻟﻤ‬ ، ‫�ﺔ‬ �‫دراﺳ‬ ‫وﺗﻢ‬ ‫�ﺄﺛﯿﺮ‬ �‫ﺗ‬ ‫�ﺎت‬ �‫ﻧﺒﻀ‬ ‫اﻟﻠﯿﺰر‬ ‫�ﻰ‬ �‫ﻋﻠ‬ ‫�ﻮاد‬ �‫اﻟﻤ‬ ‫�ﺔ‬ �‫ﻛﻤﯿ‬ ‫�ﻄﺢ‬ �‫اﻟﺴ‬ ‫�ﺔ‬ �‫وطﺒﻮﻏﺮاﻓﯿ‬ ‫�ﺮﯾﺔ‬ �‫اﻟﺒﺼ‬ ‫و‬ ‫�ﺔ‬ �‫اﻟﺘﺮﻛﯿﺒﯿ‬ ‫�ﺎﺋﺺ‬ �‫واﻟﺨﺼ‬ ‫�ﻠﺔ‬ �‫اﻟﻤﺴﺘﺄﺻ‬ ‫�ﯿﻤﺎت‬ �‫ﻟﺠﺴ‬ ZnO ‫�ﺔ‬ �‫اﻟﻨﺎﻧﻮﯾ‬ , ‫�ﺚ‬ �‫ﺣﯿ‬ ‫�ﺎدة‬ �‫اﻟﻤ‬ ‫�ﺔ‬ �‫ﻛﻤﯿ‬ ‫أن‬ ‫�ﺬري‬ �‫اﻟ‬ ‫�ﺎص‬ �‫اﻻﻣﺘﺼ‬ ‫�ﺎﺋﺞ‬ �‫ﻧﺘ‬ ‫�ﺮت‬ �‫أظﮭ‬ ‫�ﻠﺔ‬ �‫ﻣﺴﺘﺄﺻ‬ ‫�ﺐ‬ �‫ﺗﺘﻨﺎﺳ‬ ‫اﻟﻨﺒﻀﺎت‬ ‫ﻋﺪد‬ ‫ﻣﻊ‬ ‫ﻣﺒﺎﺷﺮة‬ ‫اﻟﻠﯿﺰر‬ , ‫و‬ ‫اﻟﺬرﯾﺔ‬ ‫اﻟﻘﻮى‬ ‫ﻣﺠﮭﺮ‬ ‫ﻧﺘﺎﺋﺞ‬ ‫ﺑﯿﻨﺖ‬ ‫أن‬ ‫اﻟﻨﺎﻧﻮﯾ�ﺔ‬ ‫ﻟﻠﺠﺴ�ﯿﻤﺎت‬ ‫اﻟﺤﺒﯿﺒﻲ‬ ‫اﻟﺤﺠﻢ‬ .‫اﻟﻨﺒﻀﺎت‬ ‫ﻋﺪد‬ ‫زﯾﺎدة‬ ‫ﻣﻊ‬ ‫ﺗﻘﻞ‬ ‫واظﮭﺮت‬ ‫ﺑﯿﻨﻤ�ﺎ‬ ‫اﻟﻨﺒﻀﺎت‬ ‫ﻋﺪد‬ ‫زﯾﺎدة‬ ‫ﻣﻊ‬ ‫اﻷزرق‬ ‫اﻟﻠﻮن‬ ‫ﻧﺤﻮ‬ ‫إزاﺣﺔ‬ ‫ﺣﺪوث‬ ‫اﻟﺒﺼﺮﯾﺔ‬ ‫اﻟﺨﺼﺎﺋﺺ‬ ‫ﻧﺘﺎﺋﺞ‬ ‫اﻟﻠﯿﺰرﯾﺔ‬ ‫اﻟﻨﺒﻀﺎت‬ ‫ﻋﺪد‬ ‫ﻓﻲ‬ ‫اﻟﻨﻘﺼﺎن‬ ‫ﻣﻊ‬ ‫اﻷزرق‬ ‫اﻟﻠﻮن‬ ‫ﻧﺤﻮ‬ ‫إزاﺣﺔ‬ ‫اﻟﻄﯿﻔﯿﺔ‬ ‫اﻻﻧﺒﻌﺎﺛﯿﺔ‬ ‫ﻧﺘﺎﺋﺞ‬ ‫أظﮭﺮت‬. 198 https://doi.org/10.30684/etj.32.2B.2 2412-0758/University of Technology-Iraq, Baghdad, Iraq This is an open access article under the CC BY 4.0 license http://creativecommons.org/licenses/by/4.0
