Describe the role of melanocytes in skin pigmentationĪlthough you may not typically think of the skin as an organ, it is in fact made of tissues that work together as a single structure to perform unique and critical functions.Describe the role of keratinocytes and their life cycle.Identify and describe the hypodermis and fascia.Describe the layers of the epidermis and dermis.Describe the layers of the skin and the functions of each layer.Identify the components of the integumentary system.The correct, textbook terminology is luminophore, not lumophore, although the latter term has been frequently used in the chemical literature.By the end of this section, you will be able to:ĭescribe the layers of the skin and the functions of each layer

Luminophores can be observed in action in fluorescent lights, television screens, computer monitor screens, organic light-emitting diodes and bioluminescence.

There are also purely inorganic luminophores, such as zinc sulfide doped with rare-earth metal ions, rare-earth metal oxysulfides doped with other rare-earth metal ions, yttrium oxide doped with rare-earth metal ions, zinc orthosilicate doped with manganese ions, etc. Most luminophores consist of conjugated π systems or transition-metal complexes. Examples include transition-metal complexes such as tris(bipyridine)ruthenium(II) chloride, whose luminescence comes from an excited (nominally triplet) metal-to-ligand charge-transfer (MLCT) state, which is not a true triplet state in the strict sense of the definition and colloidal quantum dots, whose emissive state does not have either a purely singlet or triplet spin. However, some luminophores cannot be classified as being exclusively fluorophores or phosphors. Luminophores can be further classified as fluorophores or phosphors, depending on the nature of the excited state responsible for the emission of photons.

Luminophores can be either organic or inorganic. In chemistry, a luminophore (sometimes shortened to lumophore) is an atom or functional group in a chemical compound that is responsible for its luminescent properties.
