Special Issue Information
Dear Colleagues,
Nanomaterials, that is, materials with at least one dimension under about a hundred nanometers, a dimension much smaller than optical wavelengths in the visible spectrum, have contributed to a paradigm change in nonlinear optics, opening routes to applications ranging from sensing and communications to tissue imaging or health, to name a few.
Nanomaterials can take many different aspects, from dielectric and plasmonic nanoparticles to two-dimensional nanoflakes or organic assemblies as well as their composites. Hence, the diversity in their physical properties is extremely rich and allows for a large range of possibilities to adapt them to suit application needs. Optical resonances are well-known examples of such tailored properties, but size and shape may constitute others. Different approaches have been developed in order to achieve this task, from bottom–up chemical synthesis routes to lithography-based top–down techniques. If these human-made architectured nanomaterials known as metamaterials are the most common ones, mature-based ones can nevertheless be found, and their use must probably be further developed.
The present Special Issue intends to present the current state of the art in the field, focusing on the nanomaterial nonlinear optical properties, as well as their use in applications involving a nonlinear optical process. Second-order processes such as second harmonic generation as well as third-order processes like two photon excited fluorescence are the most described ones, but sum frequency generation or Kerr effects also present potential alternatives.
I firmly believe that your contribution to this Special Issue on this topic will help the community to achieve a complete and useful overview of the most recent advances in the field.
Thank you.

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. Nanomaterials 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 2900 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.
