Preface
“Meditationis est perscrutari occulta; contemplationis est admirari perspicua . . . Admiratio generat qusestionem, qusestio investigationem, investigatio inventionem” once wrote Hugo de S. Victoke and possibly described best the life span of the rare earths since the Swedish Army Lieutenant, C. A. Arrhenius’ discovery of an unusual black mineral at Ytterby in 1787. Since then the rare earths have passed through the machinery of various phases of physical science. Europium as a member of the rare earth family shows characteristics of the series as a whole as well as some typical behaviour of its own due to the presence of its six / electrons i.e., one less than the half-filled shell. This present volume attempts to provide an understanding of the various aspects of its chemical and physical behaviour. In doing so, it is hoped to provide the reader with more than just a list of the complete bibliography on the subject, and I have tried to review the literature for it’s interesting features, balancing the experimental facts with the help of the minimum amount of theory as far as possible. Experience has shown us that the trend of inorganic research has changed during the past years and one frequently needs some understanding of chemical spectroscopy and quantum mechanics to be able to appreciate the developments in this field and to interpret the wealth of experimental data. The reader is referred to B. G. Wybourne’s book: Spectroscopic Properties of Rare Earths (ref. [455]), and B. R. Judd’s book: OperatorTechniquesinAtomicSpectroscopy (ref. {482]),for detailed theoretical treatment of the subject.
The first two chapters of this book are devoted to the historical and mineralogical aspects of rare earths followed by seperation techniques. It is obvious that these two chapters cannot be limited only to the discussion of europium. Hence, the whole of the rare earth family has been treated with especial emphasis towards europium. Chapters three to five describe exclusively the chemical behaviour of europium and also the interesting features of its complexes and alloys. However, where necessary, mention of other rare earths has been made. The spectroscopic properties, both absorption and fluorescence, are dealt with in chapter six, which is followed by an account of the possible uses of europium in the last chapter.
I am extremely grateful to the Editor of Journal of the American Chemical Society, Messers John Wiley and Sons and Dr. R. S. Roth of

Preface
the U. S. National Bureau of Standard for giving kind permission for the reproduction of Figs. 3, 11 and 13—16. Dr. Roth was kind enough to send me copies of Figs. 13—16. Miss Cropper has kindly and very painstakingly drawn the rest of the figures in the book. I especially wish to acknowledge the great help of Mr. R. Wootton for reading the manuscript and making helpful comments. Finally, I would like to thank my wife who beyond the call of duty, has typed the manuscript of rather complicated nature, and without whose help it would not have been possible to prepare this monograph.
