Synthesis, characterization and prospective applications of nitrogen-doped graphene: A short review

Title: Synthesis, characterization and prospective applications of nitrogen-doped graphene: A short review Authors: Yadav, Roshni Dixit, C.K. Keywords: Graphene;Nitrogen doping;Nanoelectronics;Electrochemical biosensing;Energy storage Issue Date: 2017 Publisher: H. : ĐHQGHN Abstract: Graphene is a high crystalline material possessing the high electronic qualities. Doping of nitrogen in graphene is to tailor/control the electronic, chemical and structural properties of graphene by manip-ulating it through the means of doping such as its surface area and functional sites. Different configu-rations i.e. Pyridinic N, Pyrrolic N, Graphitic N are obtained while doping nitrogen into graphene. This review paper focusses on various synthesis and characterization techniques for the analysis of structural configurations of the nitrogen-doped graphene and its potential applications in variousfields such as nanoelectronics, energy storage and electrochemical biosensing Descr

Synthesis, photoluminescence and forensic applications of blue light emitting azomethine-zinc (II) complexes of bis(salicylidene) cyclohexyl-1,2-diamino based organic ligands

Title: Synthesis, photoluminescence and forensic applications of blue light emitting azomethine-zinc (II) complexes of bis(salicylidene) cyclohexyl-1,2-diamino based organic ligands Authors: Srinivasa, M. Vijayakumar, G.R. Mahadevan, K.M. Nagabhushana, H. Bhojya Naik, H.S. Keywords: Azomethine-zinc (II) complexes;Photoluminescence;OLED;Salicylaldehyde;2-Hydroxy-1-naphthaldehyde;Fingerprint Issue Date: 2017 Publisher: H. : ĐHQGHN Abstract: Various azomethine-zinc(II) complexes(3a-c)of bis(salicylidene)cyclohexyl-1,2-diamino organic ligands were synthesized by one pot reaction of salicylaldehydes/2-hydroxy-1-naphthaldehyde (2 eq), cyclo-hexyl-1,2-diamine (1 eq) and zinc acetate (1 eq) in methanol solvent at reflux temperature. The syn-thesized complexes were characterized by FTIR, 1H NMR, and SEM. Their photophysical properties such as Photoluminescence (PL) and Diffused Reflectance Spectra (DRS) were studied. PL studies revealed that the emission peaks of the com
