Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation of a different wavelength. It is a form of luminescence. Fluorescence has many practical applications, including mineralogy, gemology, chemical sensors, fluorescent labelling, dyes, biological detectors, and, most commonly, fluorescent lamps. The most striking examples of fluorescence occur when the absorbed radiation is in the UV region of the spectrum and thus invisible, and the emitted light is in the visible region.

We invite investigators to contribute original research articles as well as review articles on atomic or molecular fluorescence spectroscopy. Potential topics include, but are not limited to:

• One-or two-photon excitations in the molecular systems
• UV-Vis, prompt, and delayed fluorescences (R, E, P, and B-types of delayed fluorescences)
• RAMAN scattering on fluorescence spectrum
• Phosphorescence of aromatic molecules
• Advances on applied fluorescences in medical, biomedical, and clinical engineering

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/ijp/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
