  2. Luminous paint - Wikipedia

    en.wikipedia.org/wiki/Luminous_paint

    Fluorescent paint is available in a wide range of colors and is used in theatrical lighting and effects, posters, and as entertainment for children. The fluorescent chemicals in fluorescent paint absorb the invisible UV radiation, then emit the energy as longer wavelength visible light of a particular color. Human eyes perceive this light as ...

  3. Photoluminescence - Wikipedia

    en.wikipedia.org/wiki/Photoluminescence

    These techniques can be combined with microscopy, to map the intensity (confocal microscopy) or the lifetime (fluorescence-lifetime imaging microscopy) of the photoluminescence across a sample (e.g. a semiconducting wafer, or a biological sample that has been marked with fluorescent molecules). Modulated photoluminescence is a specific method ...

  4. Luminescence - Wikipedia

    en.wikipedia.org/wiki/Luminescence

    Fluorescence, traditionally defined as the emission of light that ends immediately after the source of excitation is removed. As the definition does not fully describe the phenomenon, quantum mechanics is employed where it is defined as there is no change in spin multiplicity from the state of excitation to emission of light.

  5. Fluorescence - Wikipedia

    en.wikipedia.org/wiki/Fluorescence

    Fluorescent paint and plastic lit by UV-A lamps . Paintings by Beo Beyond. The common fluorescent lamp relies on fluorescence. Inside the glass tube is a partial vacuum and a small amount of mercury. An electric discharge in the tube causes the mercury atoms to emit mostly ultraviolet light.

    Port with the disembarkation of Cleopatra in Tarsus (1642), by Claude Lorrain, Musée du Louvre, Paris. Light in painting fulfills several objectives like, both plastic and aesthetic: on the one hand, it is a fundamental factor in the technical representation of the work, since its presence determines the vision of the projected image, as it affects certain values such as color, texture and ...

  7. Silicon-vacancy center in diamond - Wikipedia

    en.wikipedia.org/wiki/Silicon-vacancy_center_in...

    The silicon-vacancy center (Si-V) is an optically active defect in diamond (referred to as a color center) that is receiving an increasing amount of interest in the diamond research community. This interest is driven primarily by the coherent optical properties of the Si-V, especially compared to the well-known and extensively-studied nitrogen ...

  8. Cathodoluminescence - Wikipedia

    en.wikipedia.org/wiki/Cathodoluminescence

    Thin section of quartz from a hydrothermal vein - left in CL and right in transmitted light. In geology, mineralogy, materials science and semiconductor engineering, a scanning electron microscope (SEM) fitted with a cathodoluminescence detector, or an optical cathodoluminescence microscope, may be used to examine internal structures of semiconductors, rocks, ceramics, glass, etc. in order to ...

  9. Persistent luminescence - Wikipedia

    en.wikipedia.org/wiki/Persistent_luminescence

    It is neither fluorescence not phosphorescence. [ 2 ] [ 3 ] In fluorescence, the lifetime of the excited state lasts a few nanoseconds. In phosphorescence, even if the emission lives several seconds, this is due to deexcitation between two electronic states of different spin multiplicity .
