From the PREFACE: THE series of investigations described in this memoir was begun in 1903. The authors believed that by the use of quantitative methods and particularly by the application of the spectrophotometer to the study of the spectra of fluorescent and phosphorescent substances, something of definite value might be added to the existing information concerning luminescence. Spectroscopy, whether visual or photographic, is a method of high precision where applied to line spectra, but in the case of the broad bands of the spectra of fluorescent solids and liquids it affords but little information beyond the approximate width and general location of the bands. The spectrophotometer, on the other hand, enables the observer to determine the distribution of intensities throughout the emission bands and the coefficients of absorption for the various wave-lengths of the corresponding absorption bands. From the curves expressing the results of such measurements, moreover, it is possible to locate with considerable accuracy the crests of the bands. One may thus attain some detailed knowledge of the laws of the radiation of luminescence, compare luminescence with the radiation due to temperature, and obtain a basis for theoretical discussion. A number of important portions of the work described in this volume have been carried out at our suggestion by Doctors Frances G. Wick, C. A. Pierce, Percy Hodge, and C. W. Waggoner, and by Messrs. H. E. Howe and Carl Zeller. To these investigators and also to Prof. W. R. Orndorff, who has repeatedly aided us by undertaking the preparation of fluorescent compounds and by suggestions concerning the chemical aspects of the problem, we desire to express our indebtedness. The recent exhaustive, thorough, and discriminating review of the very large literature relating to luminescence published by Professor Kayser (H. Kayser, Handbuch der Spektroskopie, Bd. iv, Kap. v and vi) in his Handbook of Spectroscopy, makes any extended bibliographic or historic treatment here unnecessary and we have therefore given only such references to previous researches as bear directly upon the subjects under consideration. The subject-matter contained in the several chapters appeared from time to time, as each portion of the work reached completion, in a series of papers hi the Physical Review. In gathering this material together in a single treatise we have recast and rearranged it, but have preserved the original form of presentation in so far as it was found to be consistent with our views after the completion of the work. Grants which were received from the Carnegie Institution of Washington in 1905, 1909, and 1910 have greatly facilitated the prosecution of the experiments described in this memoir and of others now in progress and have furthered the preparation for investigations which it is proposed to undertake in the near future.

Since the first date of publication of this book in 1991, the subject of phosphors and luminescence has assumed even more importance in the overall scheme of technological development. Many new types of displays have appeared which depend upon phosphors in their operation. Some of these were pure conjecture in 1991 but are a reality in 2004. Descriptions have been included of the newer (as well as the older) types of displays in this edition along with an annotated portrait of the phosphors used in each category. Many of these new light sources promise to displace and make obsolete our current light sources, such as incandescent lamps, fluorescent lamps and the ubiquitous colour Cathode Ray Tube now used in TV and computer monitors. The importance of solid state science are summarized in the introductory chapters of this edition, and many of the chapters have been completely rewritten or revised. Each chapter has a special contribution to make in the overall understanding of the solid state science of phosphors and luminescence. - Introduces the reader to the science and art of preparing inorganic luminescent materials. - Describes how and why luminescent materials exhibit such specific intrinsic properties. - Describes the science of the solid state and presents the exact formulas and conditions required to make all of the phosphors known at that time.

Just three women qualified for a professorship in physics in Germany before the Second World War. All three began their careers with great promise; all three had to leave Hitlers Germany, among them Hertha Sponer. An ambitious girl, she had to struggle to achieve the education she craved, culminating in a Ph.D. at the University of Gttingen. There followed an apprenticeship in Berlin, and work under the aegis of James Franck, around the time he received the Nobel Prize. Their academic world was shattered by the Nazis. Sponer reluctantly embarked on a new life in North Carolina. She succeeded as Professor of Physics at Duke University. She became a recognized authority on the electronic spectra of aromatic molecules (benzene and derivatives). Late in life, she became the second wife of James Franck.

Over the last several decades, the number of people who are actively involved in the hobby or science of mineral collecting has grown at an increasing pace. In response to the growing demand for informa tion which this large and active group has created, a number of books have been published dealing with mineralogy. As a result, the reader now has a choice among mineral locality guides, field handbooks, photo collections, or books dedicated to the systematic description of minerals. However, as interest in mineralogy has grown, as collectors have become increasingly knowledgeable and aware of mineralogy in its many facets, the need for more specialized information has also grown. Nowhere is this need greater than in the subject of the fluorescence of minerals. The number of collectors who now main tain a fluorescent collection is substantial, interest is constantly increasing, and manufacturers have recently responded by the intro duction of new ultraviolet equipment with major improvements in utility and performance. Yet when the collector searches for any information on this subject, little will be found. He or she will seek in vain for the answers to questions which present themselves as in terest in fluorescent minerals grows and matures. Which minerals fluoresce? Where are fluorescent minerals found? What makes a mineral fluoresce? Why does ultraviolet light produce fluorescence? What is an activator, and how does it contribute to fluorescence? On these matters, the available mineralogy books are largely silent.
