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 اولOptical and Dielectric studies in zirconium(IV) tungstate nanoparticles prepared by chemical coprecipitation method
Nanoparticles of zirconium(IV) tungstate are prepared by chemical co-precipitation method. Thecharacterizations have been carried out by TG/DTA, DSC, AFM, XRD, FTIR and UV-Vis spectrum. PLspectrum shows two emission bands at 350 nm and at 477 nm. The effects of frequency on the dielectricbehavior and ac electrical conductivity have been studied. The dielectric constant is found to be 119.43 at1...
متن کاملStructural and electrical properties of In-doped vanadium oxide thin films prepared by spray pyrolysis
The In-doped vanadium pentoxide nanostructures with different doping levels including 0, 10, 20 and 30 at.% were prepared by the spray pyrolysis technique. The prepared thin films were characterized by the x-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results revealed that the films were crystalline in tetragonal phase. Increasing the In-doping level made the structure...
متن کاملStructural and optical properties of Cerium doped Calcium Fluoride nanoparticles prepared by copercipitation
Calcium fluoride nanoparticles with special amount of cerium ion (%1) were synthesized by coprecipitation. Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), absorption and photoluminescence (PL) from CaF2Ce nanoparticles has been investigated. FTIR spectra reveal that there are some amounts of OH, NO3 and other organic functional groups on the parti...
