Upon receiving a delivery of squid so fresh it luminesces, he won't conceive of a whole new way to serve it.

Children will especially enjoy the interactive elements, like coral that luminesces when touched and sea lions that respond to visitors' movements by waving and turning.

Magnesium-Calcite is sometimes replaced by Manganese-Calcite, which luminesces bright red-orange or yellow orange. In multilayer eggs the shells will appear the same color, but the shell membrane between them tends to be replaced by manganese-calcite that luminseces bright orange. Manganese is the primary instigator of luminescence whereas iron hinders it.

Phase difference between LED output and luminescence. Typically a short duration ultraviolet lamp or laser source illuminates the phosphor coating which in turn luminesces visibly. When the illuminating source ceases, the luminescence will persist for a characteristic time, steadily decreasing. The time required for the brightness to decrease to 1/e of its original value is known as the decay time or lifetime and signified as \tau.

While the visible light produced by fluorescent lamps comes from a phosphor coating which luminesces at low temperature, such lamps also include metal electrodes which are heated to a very high temperature, seemingly causing the same halachic issues as incandescent lamps. However, LED lamps contain no hot metal filament and do not have the same halachic questions, though they may be halachically problematic for reasons discussed later in this article.

Comb jellies such as Euplokamis are bioluminescent, creating blue and green light, especially when stressed; when disturbed, they secrete an ink which luminesces in the same colors. Since comb jellies are not very sensitive to light, their bioluminescence is unlikely to be used to signal to other members of the same species (e.g. to attract mates or repel rivals); more likely, the light helps to distract predators or parasites. Some species of squid have light-producing organs (photophores) scattered all over their undersides that create a sparkling glow.

A. fischeri colonization of the light organ of the Hawaiian Bobtail Squid is currently studied as simple model for mutualistic symbiosis, as it contains only two species and A. fischeri can be cultured in a lab and genetically modified. This mutualistic symbiosis functions primarily due to A. fischeri bioluminescence. A. fischeri colonizes the light organ of the Hawaiian Bobtail Squid and luminesces at night, providing the squid with counter-illumination camouflage, which prevents the squid from casting a shadow on the ocean floor. A. fischeri colonization occurs in juvenile squids and induces morphological changes the squids light organ.

Fudan University, formerly romanized as Fuh Tan, was founded as Fudan Public School in 1905, by Ma Xiangbo, SJ, who had resigned from Aurora University. The two Chinese characters Fu (, means "again") and Dan (, means "morning", "light" ), meaning both "(heavenly light shines) day after day" and "Aurora Revived", were chosen by Ma on the recommendation of Yu Youren, from the Confucian Classic Shangshu Dazhuan (): "Itinerant as the twilight, sun glows and moon luminesces" (). The university motto "Scientia et studium, quaestīo et cogitation" comes from Analects Book 19.6 (), which means "to learn extensively and adhere to aspirations, to inquire earnestly and reflect with self-application". In 1911, during the Xinhai Revolution, the college was occupied as headquarters of the Guangfu Army and closed down for almost one year.
