ACS Applied Optical Materials is an international and interdisciplinary forum for publishing original experimental and theoretical research, including simulation and modeling, in the field of optical materials. This journal complements the ACS Applied Materials portfolio, emphasizing innovative applications and expanding the scope of existing ACS publications that focus on the fundamental aspects of the interaction between light and matter in materials science, including ACS Photonics, Macromolecules, Journal of Physical Chemistry C, ACS Nano, and Nano Letters. The scope of ACS Applied Optical Materials includes high-quality applied research that integrates knowledge from materials science, chemistry, physics, optical science, and engineering. Please note that manuscripts primarily reporting data or data applications are not suitable for publication in this journal. Research areas covered by the journal include: Materials: photonic crystals and structural colored materials, phosphors, fluorophores and dyes, metamaterials, semiconductors, heterostructures and quantum localized materials, light-manipulating microstructures and nanostructures, intermetallic compounds, two-dimensional materials, carbon materials and organic functional materials, plasmonics, photochromic and electrochromic materials, upconversion and downconversion materials, solar absorbers and concentrators, radiation scintillation materials.
