  2. Strontium aluminate - Wikipedia

    en.wikipedia.org/wiki/Strontium_aluminate

    Phosphorescent materials were discovered in the 1700s, and people have been studying them and making improvements over the centuries.The development of strontium aluminate pigments in 1993 was spurred on by the need to find a substitute for glow-in-the-dark materials with high luminance and long phosphorescence, especially those that used promethium.

    Phosphorescent pigments performance, in visible light, in dark, after 4 minutes in dark - zinc sulfide (left) and strontium aluminate (right) based materials Super-LumiNova is a brand name under which strontium aluminate –based non- radioactive and nontoxic photoluminescent or afterglow pigments for illuminating markings on watch dials ...

  5. Luminous paint - Wikipedia

    en.wikipedia.org/wiki/Luminous_paint

    Radioluminescent paint is a self-luminous paint that consists of a small amount of a radioactive isotope (radionuclide) mixed with a radioluminescent phosphor chemical. The radioisotope continually decays, emitting radiation particles which strike molecules of the phosphor, exciting them to emit visible light.

  6. Strontium - Wikipedia

    en.wikipedia.org/wiki/Strontium

    Strontium aluminate is frequently used in glow in the dark toys, as it is chemically and biologically inert. [69] Strontium salts are added to fireworks in order to create red colors. Strontium carbonate and other strontium salts are added to fireworks to give a deep red colour. [70] This same effect identifies strontium cations in the flame test.

  7. Lumibrite - Wikipedia

    The invention was patented in 1994 by Nemoto & Co., Ltd. and licensed to other manufacturers and watch brands that use different (brand) names. [2] These strontium aluminate–based phosphorescent pigments, often called lume, operate like a rechargeable light battery. After sufficient activation by sunlight, fluorescent, LED, UV (blacklight ...

  8. LSAT (oxide) - Wikipedia

    en.wikipedia.org/wiki/LSAT_(oxide)

    LSAT is the most common name for the inorganic compound lanthanum aluminate - strontium aluminium tantalate, which has the chemical formula (LaAlO 3) 0.3 (Sr 2 TaAlO 6) 0.7 or its less common alternative: (La 0.18 Sr 0.82)(Al 0.59 Ta 0.41)O 3. LSAT is a hard, optically transparent oxide of the elements lanthanum, aluminium, strontium and tantalum.
