Influence of annealing on magnesioferrite nanoparticles synthesized by a sol-gel/combustion method

Influence of Annealing on Zn1-XCuxo (X=6.27%) Thin Films by Sol-gel Method

The Zn1-xCuxO (x=6.27%) films under different annealing were prepared by the sol-gel method on grass. Using the X-ray diffraction (XRD), atomic force microscopy to study the influence of annealing on the microstructure and surface morphology of the film, the result of which shows that the annealing temperature did not change the wurtzite structure of ZnO and the film density under 400 degree an...

Surface related and intrinsic exciton recombination dynamics in ZnO nanoparticles synthesized by a sol-gel method

Morphological control of heterostructured nanowires synthesized by sol-flame method

Heterostructured nanowires, such as core/shell nanowires and nanoparticle-decorated nanowires, are versatile building blocks for a wide range of applications because they integrate dissimilar materials at the nanometer scale to achieve unique functionalities. The sol-flame method is a new, rapid, low-cost, versatile, and scalable method for the synthesis of heterostructured nanowires, in which ...

Optical and photocatalytic properties Undoped and Mn-doped ZnO nanoparticles synthesized by hydrothermal method: Effect of annealing temperature

Undoped and Mn-doped ZnO nanoparticles were successfully prepared by the hydrothermal method with different annealing temperature conditions. Structural, chemical and optical properties of the samples were studied by X-ray diffraction (XRD), Field Emission scanning electron microscopy (FESEM), UV-Vis spectrophotometry and Fourier transform infrared (FT-IR) spectroscopy. The phase purity was con...

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...
