BRAVO, José A; VALDIVIESO, Fabiola; QUIROZ, Noemí  and  VILA, José L. Luminescent compounds:: Gingerol, quinine sulphate and fluorescein, a short review  . Rev. Bol. Quim [online]. 2018, vol.35, n.4, pp.108-116. ISSN 0250-5460.

ABSTRACT Certain compounds have luminescent properties. When they are submitted to ultraviolet radiation in a certain wavelength range, electrons get excited passing thus from a fundamental energy state to a higher one. When electrons return to their basic state, they emit the excess energy under the form of radiation in the visible spectrum (390 to 750 nm). We have isolated from their natural sources or synthesized three compounds of such kind, namely gingerol, quinine sulphate and fluorescein, and we have established their yields and observed their luminescent properties. A brief bibliography is provided.
