Special Issue Information

Dear Colleagues,

People like beautiful images. Multicolor images and movies can be obtained with the use of photonic crystals. This is the reason for the development of advanced materials with photonic stop bands for show. Bright examples are natural and artificial opals. Additionally, photonic crystals can be fabricated as tunable materials; thus their images can be changed following the external conditions. Artificial opals, Bragg reflectors, and microcavities can be doped with light-emitting ions, quantum dots, and nanocrystals. In this case artificial opals, for example, can give a simultaneous compilation of the effects of iridescence and luminescence, sometimes very impressive, unpredictable, and unrepeatable.

This issue would like to attract material scientists, chemists, and physicists on the one side, and engineers of show effects on the other side, to develop technologies of multicolor images for shows. Beautiful images based on the effects of self-formation, light scattering, interference, and luminescence can compete with rainbows and other unique effects that we can observe shortly and from time to time only.

The methods of synthesizing the artificially prepared samples and their natural photographs (not drawn with a computer) will attract young scientists in their professional education in physics and chemistry. Thus the Issue can contribute to attractive and popular features of research.

It is very important for the authors to have at least one or more color photographs of the original experimental sample.

Topics include, but are not limited to, the following:

  • Synthesis and images of the photonic crystals;
  • All kinds of visible luminescence in photonic crystals and other optically anisotropic matrices;
  • Images of natural photonic crystals modified with all kinds of luminescence species;
  • Images obtained with the use of upconversion and downconversion;
  • Luminescence of dyes and other species from photonic crystals and gels;
  • Materials with tunable luminescence.

The paper reports on obtaining visually appealing images from opal matrices to artificial samples comprising regular packing of monodisperse silica globules. We show the images of iridescence, photoluminescence, and both of them simultaneously, exciting upconversion luminescence of Er3+ ions from BaTiO3 xerogel/opal matrix. Opal matrix with BaTiO3 xerogel doped with Er3+ and Yb3+ ions demonstrates upconversion luminescence under excitation with the wavelength 980 nm of the laser with the main bands ranging from 500 to 570 nm and 640–700 nm, corresponding to the transitions from the excited states 2H11/2, 4S3/2, 4F9/2, 4I9/2 to the ground state 4I15/2 of trivalent Er ions. In our view, the synthesis of opal matrices along with the generation of luminescent xerogels doped, for example, with trivalent lanthanides, is a promising approach for obtaining colorful images, always very individual and often very attractive, bringing joy and pleasure at concerts and other show business events.

A series of Er3+–Tm3+–Yb3+ tri-doped fluorophosphate glasses with different molar compositions were synthesized using the conventional melt-quenching technique, and their optical properties were measured and analyzed. Under laser excitation at 980 nm, blue, green and red upconverted emissions were observed at around 475, 545 and 660 nm, respectively. Based on the results and the energy level diagrams, energy transfer processes were proposed to explain the population mechanisms of the emitting levels. A final characterization was developed within the framework of the CIE 1931 chromaticity coordinate diagram. Varying the doping concentrations of the optically active rare-earth ions, as well as the laser pumping power, enabled modulation of the three primary colors, resulting in blue, green and relatively close to white light emissions. This tunability of the upconverted emissions highlights the potential of these fluorophosphate glasses as tunable optical devices, laser systems and visual show effects. Full article
