“…PBGs or PCs are structures whose refractive index, n, or dielectric constant, e, are periodic on a length scale of the order of optical wavelengths, which prevents light from propagating through the structure due to Bragg reflection [ 134 ]. Depending on the dimensionality of this periodicity, one can have PBGs in one, two, or three dimensions (1D, 2D, or 3D).…”

“…The cavity layer may also be doped with rare-earth ions [ 135 ], leading to exciting changes in their photoluminescence behavior. While spontaneous emission is inhibited within the stop band, where there are no photon modes available [ 134 ], within the cavity passband, the photoluminescence is enhanced by a factor of the order of the quality factor of the cavity.…”

Inorganic glass is a transparent functional material and one of the few materials that keeps leading innovation. In the last decades, inorganic glass was integrated into opto-electronic devices such as optical fibers, semiconductors, solar cells, transparent photovoltaic devices, or photonic crystals and in smart materials applications such as environmental, pharmaceutical, and medical sensors, reinforcing its influence as an essential material and providing potential growth opportunities for the market. Moreover, inorganic glass is the only material that is 100% recyclable and can incorporate other industrial offscourings and/or residues to be used as raw materials. Over time, inorganic glass experienced an extensive range of fabrication techniques, from traditional melting-quenching (with an immense diversity of protocols) to chemical vapor deposition (CVD), physical vapor deposition (PVD), and wet chemistry routes as sol-gel and solvothermal processes. Additive manufacturing (AM) was recently added to the list. Bulks (3D), thin/thick films (2D), flexible glass (2D), powders (2D), fibers (1D), and nanoparticles (NPs) (0D) are examples of possible inorganic glass architectures able to integrate smart materials and opto-electronic devices, leading to added-value products in a wide range of markets. In this review, selected examples of inorganic glasses in areas such as: (i) magnetic glass materials, (ii) solar cells and transparent photovoltaic devices, (iii) photonic crystal, and (iv) smart materials are presented and discussed.

“…Photonic bandgap (PBG) crystals are periodic dielectric structures that alternate high and low permittivity materials in order to obtain an electromagnetic stop‐band in a desired direction, depending upon the periodicity of the structure. PBG crystals were proposed in the late 1980's and since then there have been extensive theoretical and experimental works devoted to this new field in order to understand and exploit the properties of these structures (Berger, 1999; Dowling et al , 2000). The dielectric or metallic periodic structure gives rise to a forbidden band of frequencies, or photonic bandgap, which essentially changes the electromagnetic wave propagation properties through the structure.…”

Three‐dimensional photonic bandgap (PBG) structures using alumina (Al2O3) as the high permittivity material were modeled and then the structures were fabricated by Fused Deposition of Multi‐materials (FDMM) technology. A finite element method and a real‐time electromagnetic wave propagation software were used to simulate and design the layered PBG structures for applications in the microwave frequency range. The modeling predicted a 3‐D photonic bandgap in the 16.5–23.5 GHz range. FDMM provides a computer‐controlled process to generate 3‐D structures, allowing high fabrication flexibility and efficiency. Electromagnetic measurements displayed the presence of a bandgap between 17.1–23.3 GHz, showing a good agreement with the predicted values. These PBG structures are potential candidates for applications in advanced communication systems.

“…Although the traditional microfabrication techniques offer a good control over structured defects and have application in making 3D structures which diffract light in microwave range [5,6] , they are very timeconsuming and have trouble in creating photonic crystals which diffract lights in visible or near-infrared region. By contrast, the self-assembly approach, namely, assembly of the colloidal crystals, affords 3D periodic structures in a controllable, simple, and inexpensive way.…”

SiO 2 colloidal spheres were synthesized by Stöber method. In order to enhance surface charge of the SiO 2 spheres, they were modified with succinic acid. Scanning electron microscope (SEM) shows that the average size of modified SiO 2 spheres is 473 nm, and its distribution standard deviation is less than 5%; Fourier-transform infrared spectra (FT-IR) and X-ray photoelectron spectrometer (XPS) results indicate that one end of succinic acid is chemically bonded to the SiO 2 spheres through esterification; Zeta potential of the modified SiO 2 spheres in water solution is improved from −53.72 to −67.46 mV, and surface charge density of the modified SiO 2 spheres is enhanced from 0.19 to 0.94 μC/cm 2 . SiO 2 colloidal crystal was fabricated from aqueous colloidal solution by the vertical deposition method at 40℃ and 60% relative humidity. SEM images show that the sample of SiO 2 colloidal crystal is face-centered cubic (fcc) structure with its (111) planes parallel to the substrate. Transmission measurement shows the existence of photonic band gap at 1047 nm.photonic crystals, colloidal crystals, vertical deposition method, SiO 2 colloidal spheres, surface charge density Since the pioneer works of Yablonovitch [1] and John [2] , photonic crystals have received a great deal of attention because of their technological application in zerothreshold lasers, high efficiency light emitting diodes, optical switch and integrated optical waveguides, etc. [3,4] .Currently, there are two main fabrication strategies, namely, "top-down" microfabrication and "bottom-up" self-assembly. Although the traditional microfabrication techniques offer a good control over structured defects and have application in making 3D structures which diffract light in microwave range [5,6] , they are very timeconsuming and have trouble in creating photonic crystals which diffract lights in visible or near-infrared region. By contrast, the self-assembly approach, namely, assembly of the colloidal crystals, affords 3D periodic structures in a controllable, simple, and inexpensive way. When the volume concentration of highly monodispersed colloids reaches a certain value, they would like to assemble into 3D ordered structures under the effect of electrostatic repulsive force. These structures include face-centered cubic (fcc), body-centered cubic (bcc), etc., whose crystal lattice constants are in submicron range. Thus, in the past few years, remarkable advances were seen in the self-assembly of colloidal crystals to create photonic crystals in visible or near-infrared region [7,8] .Up to now, the fabrication routes for creating colloidal crystals can be roughly divided into two techniques: gravity sedimentation and solvent evaporation. For the gravity sedimentation method, crystal formation can only occur at specific colloid volume fraction, as a result, the crystal thickness is not easily controlled [9] . For the solvent evaporation method, the thickness and quality can be controlled by either varying colloid concentrations or repeating layer-by-layer...
