Abstract: Graphene oxide (GO) nano particleswere successfully prepared by modified Hummer’s method for the future application of touch screens in electronic devices, energy storage, water filtration system, medical sensor and drug delivery. Comprehensive characterizations of the properties of GO nano particles were conducted. To analyze crystal structure of GO nano particles X-ray diffraction (XRD) was done. Fourier transform infrared spectra analyzer (FTIR) was used to show the presence of oxygen containing functional groups in GO nano particles. The photoluminescence (PL) certifies that GO nano particles possessed excellent optical properties in blue and green region and a strong emission peak is observed at 532.41nm. Atomic force microscopy(AFM) shows the surface roughness and the particle size found around 40nm.Finally, GO nano particles was obtained by modified Hummer’s method.
