| phosphorescence |
Phosphorescence is the result of a radiative (light emitting) transition involving a change in the spin multiplicity of (in most cases) a molecule from excited state singlet to excited state triplet. This transition is quantum mechanically forbidden as is the transition that leads to light emission. ...

| photosensitive |
Photosensitivity is the amount to which an object reacts upon receiving photons of light. Devices that are photosensitive include the human retina and photographic film. Film is photosensitive because it has a chemical reaction when struck by light. The same process is used in the electronic device known as a photocathode, which is a surface that emits electrons when struck by light. ...

| phosphorus |
Phosphorus, (from the Greek language Phosphoros meaning "light bearing"), is the chemical element in the periodic table that has the symbol P and atomic number 15. A multivalent, nonmetal of the nitrogen group, phosphorus is commonly found in inorganic phosphate rocks and in all living cells. Due to its high reactivity, it is never found as a free element in nature. ...

| phototropism |
Phototropism or heliotropism are botanical terms for an organism response to light (in the case of heliotropism, specifically the light from the Sun). These are one of the many plant tropisms or movements in response to extermal stimuli. Growth toward a light source is a positive phototropism, while the reverse is called negative phototropism or skototropism. ...
