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...

Measurement of tissue optical properties

Knowledge of the optical properties is in medicine very important for modeling of light propagation in tissue, diagnosis and therapeutical methods. The aim of a theoretical part is understanding of tissue optics and different approaches for determining optical properties in a turbid medium such as tissue. In experimental part we are designing a new method for determining optical properties abso...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

High Precision Optical Measurement Methods

I. INIRODllCTION Noncontact optical methods are appropriate for mic;ro.. and macrostructure measurements. Time of flight and phase measuring techniques with a resolution in the order of a few mm to one mm. respectively arc well introduced. Furthermore active and passive triangulation techniques arc very robust and appropriate for different applications in precision measurements. Some optical 3-...
