Photonic crystal energy storage

What is a photonic crystal?

As mentioned above, a photonic crystal is a material whose dielectric function varies periodically, therefore: where R is a lattice-translation vector, equal to l1a1 + l2a2 + l3a3 where l1, l2, and l3 are integers.

Can photonic crystal optics be useful for OPAL research?

This review presents several of these applications and an accessible overview of the physics of photonic crystal optics that may be useful for opal and inverse opal researchers in general, with a particular emphasis on the recent use of these three-dimensional porous structures in electrochemical energy storage technology.

What are photonic crystal films used for?

We believe that these single and multistacked photonic crystal films with high reflectivity have potential for a variety of applications, such as optical filters, reflectors, and anticounterfeiting optical barcodes as well as structural colorants and colorimetric sensors 10, 40, 41, 42, 43.

What if a photonic crystal is placed in an air medium?

If the photonic crystal is placed in an air medium ( n1 = 1) and a first-order resonance ( m = 1) is being measured, this equation can also be seen represented as: The authors acknowledge support from the Irish Research Council Government of Ireland Postgraduate Scholarship under award no. GOIPG/2016/946.

How are superparamagnetic non-close packed photonic crystals made?

Asher et al. assembled superparamagnetic non-close packed photonic crystals using highly charged superparamagnetic polystyrene–iron oxide composite colloidal particles, fabricated by the emulsion polymerization of styrene in the presence of ∼10 nm iron oxide particles.

How do photonic crystals affect photon propagation?

Efforts to achieve all-optical integrated circuits have led to a growing interest in the fabrication and use of photonic crystals (PhCs); PhCs have a periodic variation in dielectric function that affects the propagation of photons much like the periodic potential in semiconductors affects the flow of electrons.
