In the present work the synthesis of fullerene thin flm produced in a conventional microwave oven from the decomposition of terpenoid is reported. Te polycrystalline structure of the sample was determined by X-ray difraction (XRD); the sample showed several phases, and the main phase corresponds to fullerene ordered in a face-centered cubic structure (FCC), with a lattice parameter  = 14.16 ˚ A, with two more structures: one is orthorhombic system with lattice parameters  = 9.53 ˚ A,  = 8.87 ˚ A, and  = 8.354 ˚ A, and the other is the monoclinic system with lattice parameters  = 10.24 ˚ A,  = 7.80 ˚ A,  = 9.49 ˚ A, and  = 92.4 ∘ coexisting also with graphite 2H phase with lattice parameters  = 2.46 ˚ A,  = 6.71 ˚ A. It was observed in a scanning electron microscopy (SEM) that the sample formed thin flms of stacked carbon. Te flm thickness was measured by a SEM, and it was 140.8 to 523 nm and the macroscopic area of 12 cm 2 , whereas a high-resolution transmission electron microscopy (HRTEM) revealed that the main phase of the material is C 60 ordered in a face-centered cubic structure (FCC). In the sample surface by atomic force microscopy (AFM), islands deposited crystals were observed having symmetry 43m crystal habit associated with the tetrahedron. 1. Introduction Carbon thin flms are important for the development of appli- cations in semiconductors, nano electronics, and aerospace industry due to the physical properties of their crystal structure. Tese properties are high electric conductivity or semiconductivity, photo conductivity, and optical non- linearity [1]. Several methods are currently used for the preparation of carbon flms [2–5]. In these methods the flms are obtained in temperature conditions at ranges of 950–1250 ∘ C[6] with diferent energies from 100 to 1000 eV [7] at pressure from 1 to 5 × 10 −7 Torr [8–10] using inert atmospheres or carbon gases as control atmospheres with fowing in a continuous way to obtain small area flms with thicknesses from 500 nm to 10 000 nm with a crystalline or amorphous structure [11], making this synthesis expensive. Comparing the carbon flm precursors at present, the use of organic resins such as terpenoids has proven to be efcient in obtaining carbon flms by using techniques such as CVD [12– 17]. Comparing the chemical precursors used in the synthesis of carbon flms, it was observed that organic resins present more advantages than the inorganic precursors because some of these resins are environment friendly [18]. It is important to mention that camphor resin has been successfully used in carbon nanomaterials synthesis and also in carbon flms, graphene, carbon nanotubes, and other carbon allotropes [19, 20]. However it must be mentioned that the sample amount obtained in these experiments is very small. Based on the previous information it is necessary to look for new synthesis methods which must be not only more efective but also
