SummaryThe spectra of transmission and reflection of synthetic opal which has 3-dimensional periodic structure were measured at different orientations of incident beam relative to the sample facets. It is shown that opal behaves as «semi-metallic» photonic band gap (PBG) material in the vicinity of photon energy 2.3 eV. The synthesis of CdS microcrystals embedded in the pores of opal was made for the first time in an attempt to form a system of quantum dots. Optical spectra (reflection and… 

Enhancement of optical gain of semiconductors embedded in three-dimensional photonic crystals

The three-dimensional photonic crystals used in this study were synthetic opals, composed of submicron silica spheres, close-packed in a face-centered cubic structure with a period of 200 nm, that

Optical Characterisation of Opal Photonic Hetero-Crystals

We introduce the 3-dimensional photonic crystal heterojunction on synthesised by successive growth of one opal film on another based on the self-assembly of monodisperse polystyrene beads of

Interplay of order and disorder in the optical properties of opal photonic crystals

It is shown that the polycrystalline structure of self-assembled synthetic opals leads to an interplay of properties determined by order and disorder in the vicinity of the optical stop band. We

Structural, photonic band-gap, and luminescence properties of the opal-erbium composite

Erbium oxide and silicates were embedded in the pores of synthetic opal by using the chemical bath deposition technique. Electron-microscopic images showed the synthesized compounds to be deposited

Luminescent properties of synthetic opal

We have studied the effect of the photonic band gap on the visible luminescence of opal photonic crystals. The results indicate that the position of the photonic band gap in the luminescence and

Structure-related optical properties of luminescent hetero-opals

Light-emitting hetero-opals have been synthesized by successive crystallization of one thin opal film on top of the other from beads of two different diameters and selective impregnation of one of

Spectroscopy of the photonic stop band in synthetic opals

The photonic band gap of opals has been studied experimentally from their optical transmission spectra as a function of the incident beam orientation in the opal crystal lattice. The measurements

Control over the spectral position of the band gap of opal photonic crystals

We demonstrate that the width and spectral position of the band gap of opal photonic crystals can be controlled by varying the concentration of solution in the opal pores. An experimental technique

Strong dispersive effects in the light-scattering mean free path in photonic gaps

We have performed measurements of the scattering mean free path s in photonic crystals with different and controlled amounts of disorder. In the most perfect crystals, 1 order of magnitude chromatic



Quantum Confinement and Host/Guest Chemistry: Probing a New Dimension

Current approaches for generating nanostructures of conducting materials are briefly reviewed, especially the use of three-dimensional crystalline superlattices as hosts for quantum-confined semiconductor atom arrays (such as quantum wires and dots) with controlled inter-quantum-structure tunneling.

Optical Spectroscopy of Size Effects in Semiconductor Microcrystals

Size effects in semiconductor systems with reduced dimensions have attracted considerable attention within the last few years. Besides the well known quantum-well and quantum-wire structures(1,2),

Inhibited spontaneous emission in solid-state physics and electronics.

If a three-dimensionally periodic dielectric structure has an electromagnetic band gap which overlaps the electronic band edge, then spontaneous emission can be rigorously forbidden.

Photonic bands: Convergence problems with the plane-wave method.

It is found that when ∈(r) is sharply peaked, photonic levels become almost degenerate throughout the Brillouin zone, corresponding to standing waves.
