Ultra‐Efficient Photocatalytic Properties in Porous Tungsten Oxide/Graphene Film under Visible Light Irradiation
Recently, a growing amount of effort has been devoted to solving the widespread problem of pollution. Photocatalysts have attracted increasing attention for their widespread environmental applications. Here, a classic and simple electrospun technique is used to directly fabricate a porous a tungsten oxide nanoframework with graphene film as a photocatalyst for degradation of pollutants. The as-...
متن کاملEffects of KrF „248 nm... excimer laser irradiation on electrical and optical properties of GaN:Mg
The electrical and optical characteristics of GaN:Mg irradiated by a pulsed KrF ~248 nm! excimer laser have been studied. When an as-grown Mg-doped GaN film was irradiated by an excimer laser at an energy density of 590 mJ/cm in a nitrogen atmosphere, the hole concentration was drastically increased up to 4.42310 cm. Furthermore, a GaN:Mg thin film, which was treated by laser irradiation follow...

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 اولGraphene: Ultra‐Efficient Photocatalytic Properties in Porous Tungsten Oxide/Graphene Film under Visible Light Irradiation (Adv. Sci. 12/2015)
In article 1500116, B. Lu and co-workers successfully demonstrate the production of a high performance, highly porous WO 3 nanoframework with graphene film photocatalyst via an electrospinning method. The plentiful exposed graphene nanosheets can great adsorb RhB molecules via – stacking and reduce the recombination rate of electrons and holes.
متن کاملpH Effect on the Size of Graphene Quantum dot Synthesized by Using Pulse Laser Irradiation
In this study graphene oxide (GO) was synthesized by using Hummer’s method. Low dimension graphene quantum dot nanoparticles (GQDs) were synthesized using pulse laser irradiation. Fourier Transform-Infrared Spectroscopy (FTIR), Ultraviolet-Visible (UV-Vis) spectroscopy and photoluminescence (PL) analysis were applied to study the GQDs characteristic. Scanning electron microscopy illustrated the...
