▎ 摘　　要

Monolayer graphene and graphite thin films were fabricated on SiO2/Si substrates by organic coating and post annealing. Pure nickel (Ni) was deposited on the substrate surface as the catalyst. Then the samples were dipped in the Orange II organic solution. Raman spectroscopy measurements suggested that the Orange II organic solution resolved on the Ni surface and formed graphene and graphite thin layers during the heating process.
