Carbon nanomaterials for holography

Holography is a technique to produce and store three dimensional images. It has awakened special interest since its inception as it has applications in several field such as the production of security labels, the development of sensor, in massive storage or in metrology and microscopy. Holography is based on the recording of interfering patterns onto photosensitive materials thus creating a hologram. The light employed as well as the composition of the photosensitive materials are key elements to produce holograms of high quality. Due to their interesting electrical and optical properties, carbon nanomaterials have been widely studied for the fabrication of holograms of advanced properties. This review summarizes the use of carbon nanomaterials in holography. A short introduction of the types of holograms as well as the most common photosensitive materials is described. Finally, the emerging of new technologies different to holography for the fabrication of diffractive materials based on carbon nanomaterials is briefly presented.
