control of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولNonlinear Optical Absorption of Carbon Nanostructures Synthesized by Laser Ablation of Highly Oriented Pyrolytic Graphite in Organic Solvents
In this study, Highly Oriented Pyrolytic Graphite was ablated in various polar and nonpolar solvents by Q-switched neodymium: yttrium-aluminum-garnet laser (wavelength=1064 nm, frequency=2 kHz, pulse duration=240 ns). Then, the products were examined using Scanning Electron Microscopy and UV-Vis spectroscopy. The images showed that different carbon structures such as cauliflower-like structures...
متن کاملOptical Limiting Properties of Colloids Enhanced by Gold Nanoparticles Based on Nonlinear Refraction for Cw Laser Illumination
In this work, thermo-optical properties of gold nanoparticle colloids are studied using continuous wave (CW) laser irradiation at 532 nm. The nanoparticle colloids are fabricated by 18 ns pulsed laser ablation of pure gold plate in the distilled water. The formation of the nanoparticles has been evidenced by optical absorption spectra and transmission electron microscopy. The nonlinear optical ...
متن کاملIn situ decoration of graphene sheets with gold nanoparticles synthetized by pulsed laser ablation in liquids
The demand for nanocomposites of graphene and carbonaceous materials decorated with metallic nanoparticles is increasing on account of their applications in science and technology. Traditionally, the production of graphene-metal assemblies is achieved by the non-environmentally friendly reduction of metallic salts in carbonaceous suspensions. However, precursor residues during nanoparticle grow...
متن کاملAfterglow Properties of Silica-Capped Sr2MgSi2O7:Eu,Dy Nanoparticles Prepared by Laser Ablation in Ethanol
The effect of silica-capping on the afterglow property of Sr2MgSi2O7:Eu,Dy nanoparticles was investigated. Sr2MgSi2O7:Eu,Dy nanoparticles were prepared by laser ablation in liquid. Afterglow nanoparticles were capped with silica using Stöber method. A dense silica capping layer was achieved after 4 hours of reaction. Silica-capping of the afterglow nanoparticles improved the particles’ afterglo...
