Some fluorite, particularly the variety chlorophane (aka pyroemerald and cobra stone), may become very faintly luminescent simply from the heat of one's hand. Chlorophane is unusual for combining the properties of thermoluminescence, triboluminescence, phosphorescence, and fluorescence; it will emit visible spectrum light when rubbed, or ...

Halogeno-platinum compounds are among the most potent respiratory and skin sensitisers known, therefore it is vital that exposure via the skin and by breathing contaminated air is carefully controlled.
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.

In phosphors and scintillators, the activator is the element added as dopant to the crystal of the material to create desired type of nonhomogeneities.. In luminescence, only a small fraction of atoms, called emission centers or luminescence centers, emit light.
You'll never find someone who loves Ragdoll cats like one woman does. The vet tech was so excited when she saw there was a Ragdoll on the schedule for that day.
