photoluminescence

/pho·to·lu·min·es·cence/ (-loo″min-es´ins) the quality of being luminescent after exposure to light or other electromagnetic radiation.

photoluminescence

(fō″tō-lū-mĭ-nĕs′ĕns) [″ + L. lumen, light]
The power of an object to become luminescent when acted on by light.

luminescence

Emission of light by certain substances resulting from the absorption of energy (e.g. from electrical fields, chemical reaction, or other light), which is not due to a rise in temperature (unlike incandescence). The emitted radiation is characteristic of the particular substance. When the light emitted is due to exposure to a source of light the process is usually called photoluminescence. When the light emitted is due to either a high-frequency discharge through a gas, or to an electric field through certain solids such as phosphor which is used in fluorescent lamps, television picture tubes, etc., it is called electroluminescence. See bioluminescence; fluorescence; incandescence; fluorescent lamp; phosphorescence.

The incentive to use an inorganic additive as opposed to already well known oxygen photoluminescence quenching sensors based on different Pt or Ru complexes, stems from the fact that the latter needs to be incorporated inside the package separately, usually as a separate glued film because of intolerance to extrusion temperatures, which are experienced by the packaging material itself during manufacturing (~190-230 [degrees]C of LDPE [5]).
