Solution: a. Luminescence is an umbrella term for those kinds of events where light emission is not the result of high temperatures. This article depicts the different forms of luminescences and goes into detail in the case of fluorescence. Relevant technical terms describing a fluorochrome, like quenching, bleaching or quantum yield, are explained in the second part of the article to give detailed insights into basic characteristics of fluorescent illumination.
