All of its exceptional properties have opened up new avenues for the use of graphene in nano-devices and nano-systems, which initiated its prominent use as a material for drug targeting.graphene ( fig. 1) is a hexagonal structure consisting of sp 2 hybridized carbon atoms [21], described by some as the 'mother' [22] of all graphitic carbon materials due to it essentially being the building block for carbon nanotubes (effectively 'rolled up' graphene sheets) and graphite (stacked graphene sheets held together by strong van der …Feb 19, 2015 · Review Article; Published: 19 February 2015; The photoluminescence mechanism in carbon dots (graphene quantum dots, carbon nanodots, and polymer dots): current state and future perspective. Shoujun Zhu 1, Yubin Song 1, Xiaohuan Zhao 1, Jieren Shao 1, Junhu Zhang 1 & Bai Yang 1 Nano Research volume 8, pages 355–381 (2015)Cite this article This review article aims to present an overview of the advancement of research in graphene, in the area of synthesis, properties and applications, such as field emission, sensors, electronics, and energy. Wherever applicable, the limitations of present knowledgebase and future research directions have also been highlighted. Keywords:The thermal conductivity of graphene is around (5 × 103 W/mK), henceforth 10 times higher than that of copper (401 W/mK). Graphene's electron mobility has a conductivity of 106 S/m, and resistance of 31 Ω/sq. which accounts for ultra-high mobility of (2 × 105 cm2 /V.s) that is 140 more than that of silicon.Although several review articles had been written on various aspects of graphene, none of these articles covers wide spectrum of synthesis-property-application correlation of graphene. There is also no demonstration of graphene as potential substrate for Raman enhancement in these review articles.
