This work deals with the synthesis, characterization, and application of carbon nanoparticles (CNP) adorned graphene oxide (GO) nanocomposite materials. Here we mainly focus on an emerging topic in modern research field presenting GO-CNP nanocomposite as a infrared (IR) radiation detector device. GO-CNP thin film devices were fabricated from liquid phase at ambient condition where no modifying treatments were necessary. It works with no cooling treatment and also for stationary objects. A sharp response of human body IR radiation was detected with time constants of 3 and 36 sec and radiation responsivity was 3 mAW−1. The current also rises for quite a long time before saturation. This work discusses state-of-the-art material developing technique based on near-infrared photon absorption and their use in field deployable instrument for real-world applications. GO-CNP-based thin solid composite films also offer its potentiality to be utilized as p-type absorber material in thin film solar cell, as well.

Downloaded by [University of Nebraska, Lincoln] at 03:05 10 October 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 We studied the elemental analysis, structural morphology, mechanical, and electrical properties of carbon nanoparticles synthesised from diesel. The spherical carbon particles size in the range of about 10 to 80 nm in diameter was observed in SEM studies which were identified by AFM study as an aggregation of carbon particles of average size 2.5 nm. The surface rms of carbon nanoparticle thin film (CNTF) was measured directly by AFM and found 0.22 nm. The DMT elastic modulus of carbon nanoparticles (CNP) was measured by PeakForce QNM mode of AFM. The minimum and maximum elastic modulus was measured of 0.40 GPa and 43.89 GPa respectively. The resistivity, conductivity, magneto resistance, mobility and average Hall coefficient were measured by 'Ecopia Hall-effect measurement system' by 4-point Van der Pauw approach at ambient condition. We demonstrated I-V characteristic at the Indium/CNTF thin film interface which is accompanied by rectifying behavior.
