Continuing the series of articles on spectroscopy, we return principally to the UV-visible area of the spectrum, but this time to the science of luminescence (fluorescence and phosphorimetry), in all its many forms. Given the diversity of the application areas and instrument types available, in such an article we can only briefly give an overview of the topic and interested parties are, therefore, recommended to follow-up the listed references for more in-depth discussion on the points raised.

The Irish writer George Bernard Shaw once said: “England and America are two countries divided by a common language”. Whilst this statement generally refers to the over 4000 words in everyday use in the United States that are not in British English, in the scientific world “is it metre or meter”, or for spectroscopists, nanometre or nanometer?
However, irrespective of that debate, whatever the spelling, terms such as these have associated definitions, found in various reference texts, such as dictionaries, vocabularies or databases, and if we cannot agree on the spelling, what chance of achieving consistency in definition?
Fortunately, help is at hand, and it is the recent introduction of a “Concept Database” by ISO which has prompted this article.
Detailed below are just a few of the “databases” now available, and examination of the term “Resolution” is used as an example of each.
