“…The basic recording mechanism in such samples is attributed to the photo-crosslinking process of PVA when mixed with metallic salts. During the photo-crosslinking process there are two different Fe pathways: and active Fe 3+ and an inactive Fe 2+ [ 41 , 42 , 43 ]. Salts of copper (II) chloride dihydrate CuCl 2 (2H 2 O) show photosensitivity and the ability to conduct electricity.…”

Nopal Cactus (Opuntia Ficus-Indica) as a Holographic Material

2012

The nopal cactus (Opuntia ficus-indica) releases a substance through its mucilage, which comes from the degradation of pectic substances and chlorophyll. Combined in a polyvinyl alcohol matrix, this substance can be used as a recording medium. The resulting extract material has excellent photosensitizer properties, is easy to handle, has a low cost, and low toxicity. This material has the property of self-developing, and it can be used in holographic applications. The polyvinyl alcohol and extract from the nopal cactus was deposited by a gravity technique on a glass substrate, which dried to form a photosensitive emulsion. We show experimental results on a holographic grating using this material, written by a He-Cd laser (442 nm). We obtained diffraction gratings by transmission with a diffraction efficiency of approximately 32.3% to first order.

“…To our knowledge, little is available in the literature regarding the analysis of PVA doped with metal salts for possible use as a holographic and conductive material [21,22]. This manuscript presents an investigation of the optical and electrical properties of FeCl 3 -PVA samples with varied concentrations of FeCl 3 .…”

Abstract:We show experimentally that the metallic salt, FeCl 3 , at different concentrations, provides photosensitivity and conductivity characteristics with poly(vinyl alcohol) material. The holographic recording in this photosensitive material was made in real time.The effect of applied voltage on holographic diffraction gratings in the recording process and the changes in their diffraction efficiency, depending on their composition, are shown. In addition, we describe the photo-mechanism, physicochemical processes, and water condensations involved in changes of the formation of images due to applied voltage. The results suggest that polymers doped with metallic salts may have potential as inexpensive photosensitive materials that are easy to work under normal laboratory condition.
