Special Issue Information

Dear Colleagues,

This Special Issue of Materials is devoted to the “Optical Properties of Holographic Polymer-Based Composites”. Holographic polymer-based composites are polymers in which holograms can be recorded. Those materials are increasingly used to fabricate a large variety of devices ranging from simple passive optical components (filters, sensors) to complex active optical components (organic lasers, chem-biofunctionalized devices) to be used in several research fields, ranging from all-optical active and passive photomobile devices to solar concentrators or optical components for large area telescopes. Mono- or multidimensional patterned polymers are continuously developing due to their unique flexibility, low cost, easy processability, and functionalization. The study of their optical properties is of fundamental importance for the development of new and better-performing mixtures. This Special Issue is intended to enable scientists and engineers to exchange their latest theoretical, experimental, and computational knowledge concerning the optical properties of holographic polymer-based composites and their possible applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We report on highly transparent holographic phase transmission volume gratings recorded in the visible region at λ = 532 nm. The maximum measured diffraction efficiency is higher than 80% with a grating pitch of Λ≈ 300 nm and a refractive index modulation Δn ≈ 0.018. To obtain these results, we used a holographic mixture based on multi-reticulated acrylate and haloalkanes (1-bromo-butane and 1-bromo-hexane) and a synergic combination of camphore-quinone, which has a maximum absorbance at c.a. 470 nm, and R6G, here used as co-initiator, to efficiently initiate the photo-polymerization process. High transparent and high efficient holographic structures based on polymers can find applications in many research fields including integrated optics, sensors, high density data storage and security.
