Electro-optical properties of gadolinium molybdate

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...

Synthesis of Polymers with Electro-optical Properties

The electro-optical properties of organic and polymeric materials are regarded as holding potential for developments in charge storage, analytical sensors, electroluminescent devices, optical data processing and integrated optics. For example, nowadays it is clear that sensor sensitivities and specificity can be increased by using redox polymers [1] or that the parameters characterizing the rel...

Nonlinear optical properties of push–pull polyenes for electro-optics

Improved nonlinear organic chromophores of varying conjugation length with either thiobarbituric acid or 3-dicyanomethylene-2,3-dihydrobenzothiophene-1,1-dioxide (FORON® Blue) acceptors have been synthesized and investigated for their nonlinear optical properties. Very large quadratic hyperpolarizabilities b(22v; v, v) have been found, up to 25,700 3 10248 esu at l 5 1.91 mm. In a guest–host po...

Crystal defects and electro-optical properties of D-KDP

2014 This article presents a qualitative approach of the relationship between the occurrence of crystal defects and the disturbances of the induced birefringence which appear during the operation of (001) D-KDP solid-state light-valves. The crystal defects are ascribed to growth or seed effects, and both contributions to the above disturbances are discussed. On this basis, conclusions are drawn...
