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 اولAll-optical phase-change memory in a single gallium nanoparticle.
We report on the first demonstration of a quaternary-logical resonatorless optical memory element with information encoded in the structural phase of a single 80 nm gallium nanoparticle. The size of the memory element is comparable with bits in next-generation hard disks, and radically smaller than previously suggested memories exploiting optical resonators. Furthermore, the energy required for...
متن کاملNonlinear Responses and Optical Limiting Behavior of Ag Nanoparticle Suspension
In this study, the nonlinear optical properties and optical limiting performance of the silver nanoparticles (AgNPs) in distilled water are investigated. The nonlinear absorption coefficient of the colloid is measured by the Z-scan technique. The optical limiting behavior of the AgNP suspension is investigated under exposure to nanosecond laser pulses at 532 nm. The results show that nonlinear ...
متن کاملStructural, Optical and Defect State Analyses of ZnO Nanoparticle Films
Synthesis of ZnO nanostructures films by a co-precipitation followed by the deposition processed onto a glass substrate by spin-coating technique was carried out. The effect of annealing temperatures (from 250 to 325 °C for 30 min) on the structural and optical properties of the ZnO films have been investigated. The structural studies reveal that ZnO films are polycrystalline with hexagonal wur...
