Hybrid Plasmonic–Photonic Nanostructures: Gold Nanocrescents Over Opals

“…in sensors, in electrically pumped microcavities, polariton lasers, white light OLED) . Nowadays, a great effort is also devoted to the combination of PhC and plasmonic structures to study novel phenomena such as directional enhancement of fluorescence, negative refraction, omnidirectional diversion, refractive index tuning and cloaking at visible frequencies …”

“…From a fundamental point of view, such systems allowed to test light localization effects at the edges of the photonic stop band . Metal inverse opal photonic crystals have also been investigated, but in this case it is very difficult to obtain a uniform infiltration of the opal template, thus reducing the possibility of controlling the plasmonic properties . Continuous metallic films supported on the top/bottom layer of opals or on microsphere monolayers have also been investigated .…”

Nonlinear diffraction and second-harmonic generation enhancement in silicon-opal photonic crystals

“…One of prospective directions of the use of threedimensional ͑3D͒ photonic crystals of opals 1,2 is their impregnation by semiconductor, [3][4][5][6][7][8] metallic, 9,10 or magnetic 11 materials with the final goal to fabricate photonic crystals with complete photonic band gap ͑PBG͒ or with PBG tunable under external impacts. The dielectric function periodicity imposed by initial opal matrix is utilized for the control of the optical field propagation inside such composite photonic crystals.…”

Hollow Disc and Sphere-Shaped Particles from Red Blood Cell Templates

“…Colloidal particles with specific shape and function [1,2] are currently a subject of intense investigation for the development of pigments [3], microcapsules [3,4], guided drug carriers [5,6], synthetic opals [7], transparent metals [8], photonic crystals [7,8], thin-film transistors, organic light emitting diodes [9], solar cells [10,11], and tunable lasers [12].…”

“…The colloidal nature of RBCs and their unique shape motivated us to fabricate metallic colloidal particles using them as templates. Several potential commercial applications are envisioned [1][2][3][4][5][6][7][8][9][10].…”
