Concentration Quenching of Fluorescence in Chlorophyll Solutions
Nature, 1948IN a paper concerned chiefly with the results of measurements of the self-quenching of the fluorescence of solutions of aromatic hydrocarbons1, Weiss and Weil-Malherbe report a few measurements on the self-quenching of ethyl chlorophyllide solutions.

Chlorophyll Fluorescence Terminology: An Introduction
2010The terminology used to describe the various components of variable chlorophyll fluorescence has evolved as our understanding of variable chlorophyll fluorescence has increased. For the newcomer to in vivo chlorophyll a (chl-a) fluorescence studies one of the most confusing aspects can be the large number of terms and notations used, many of which ...

Lifetime of the long-wavelength chlorophyll fluorescence
Biochimica et Biophysica Acta, 1963The fluorescence lifetime of chlorophyll in vivo and in vitro was measured with a phase fluorimeter. The lifetime in vivo of the long-wavelength emission (730 mμ) which appears at low temperature was 3.1 mμsec. It is concluded that this emission is fluorescence rather than phosphorescence as had been previously reported by Brody.

Chlorophyll Fluorescence Applications in Microalgal Mass Cultures
2010Chlorophyll (Chl) fluorescence has become one of the most common and useful techniques in photosynthetic field research. Its non-invasiveness, sensitivity and the wide availability of reliable instruments, also makes it a convenient and suitable technique in microalgal biotechnology to monitor a culture's photosynthetic performance.

Флуоресценция хлорофилла – один из наиболее широко применяемых и эффективных методов, используемых во многих областях научных исследований, т. к. она представляет собой неразрушающий объективный способ забора проб для изучения некоторых аспектов кислородного фотосинтеза. Поглощаемая листьями световая энергия может подвергнуться одному из трех процессов:

Nonphotochemical Quenching of Chlorophyll Fluorescence
1996Measurement of chlorophyll fluorescence is an invaluable method for examining the interaction of photosynthetic organisms with their environment and for the non-invasive probing of the metabolism of the chloroplast (Krause & Weis, 1991; Horton & Bowyer, 1990).

Carotenoid-sensitized Fluorescence of Chlorophyll in vitro
Nature, 1958IT is well established that light absorbed by carotenoids can contribute to photosynthesis, phototaxis and the red fluorescence shown by chlorophyll A in the intact chloroplast. In Chlorella, independent measurements of both fluorescence1 and photosynthesis2 indicate a 40–50 per cent efficiency of energy transfer from β-carotene and lutein to ...
