The active laser medium (also called gain medium or lasing medium) is the source of optical gain within a laser.
In chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in molecules which are conventionally represented as having alternating single and multiple bonds, which in general may lower the overall energy of the molecule and increase stability.
In chemistry, diarylethene is the general name of a class of compounds that have aromatic groups bonded to each end of a carbon–carbon double bond.
A dye is a colored substance that has an affinity to the substrate to which it is being applied.
A dye laser is a laser which uses an organic dye as the lasing medium, usually as a liquid solution.
In organic chemistry, an electrocyclic reaction is a type of pericyclic rearrangement where the net result is one pi bond being converted into one sigma bond or vice versa.
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula or H2C.
Greek (Modern Greek: ελληνικά, elliniká, "Greek", ελληνική γλώσσα, ellinikí glóssa, "Greek language") is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean and the Black Sea.
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.
Intramolecular in chemistry describes a process or characteristic limited within the structure of a single molecule, a property or phenomenon limited to the extent of a single molecule.
Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs), are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) by fluorescence.
In organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula C6H5.
A phosphor, most generally, is a substance that exhibits the phenomenon of luminescence.
In chemistry, photoisomerization is a molecular behavior in which structural change between isomers is caused by photoexcitation.
Pterostilbene is a stilbenoid chemically related to resveratrol.
Resveratrol (3,5,4′-trihydroxy-trans-stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin produced by several plants in response to injury or, when the plant is under attack by pathogens such as bacteria or fungi.
A scintillator is a material that exhibits scintillation—the property of luminescence, when excited by ionizing radiation.
Steric effects are nonbonding interactions that influence the shape (conformation) and reactivity of ions and molecules.
Stilbene photocyclization is the coupling of two aromatic carbons in stilbenes upon ultraviolet irradiation.
Stilbenoids are hydroxylated derivatives of stilbene.
(E)-Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C6H5CH.
