Organometallic Luminescence

A Case Study on Alq3, an OLED Reference Material

• Broschiertes Buch

Produktbeschreibung

Organometallic Luminescence: A Case Study of Alq3, an OLED Reference Material contains many discoveries on Alq3, an important organometallic material to the optoelectronics community that includes insights that can be applied to other organic compounds. The book contains groundbreaking research from the author's own investigation into the Alq3 material that is based on years of experiments, the results of which initially escaped any logical explanation. The book describes a simple method based on photoluminescence to observe optical properties in Alq3, also covering the optical properties of absorption and long decay from theoretical and experimental perspectives.

Rezensionen

"This book of 352 pages, well written in English and nicely illustrated by numerous figures, contains a rich and didactical exposition of the experimental data and their analyses highlighting unseen results and many discoveries on Alq3, an important organometallic material to the optoelectronics community. Alq3 is widely used in organic light- emitting diodes (OLEDs), now commonplace in our daily lives, an inspiring invention in the vast field of display technology, as an electron- transport material and emitting layer material due to its high thermal stability, high quantum yield of fluorescence and high electron- transport ability. Especially, the original idea of the presentation has been to show groundbreaking research from the author's own investigation into the Alq3 material that is based on years of experiments, the results of which initially escaped any logical explanation. The book describes a simple method based on photoluminescence to observe complex optical properties in Alq3, also covering the optical properties of absorption, emission and long decay from theoretical and experimental perspectives with impressive details in each chapter. Most of all, this book intended for a wide audience will prove useful to students of Material Science and Engineering at all levels, and also all researchers involved in different types of optoelectronics materials. It will inspire probably the further study and appreciation of many contributions. The author, Dr. Giuseppe Baldacchini, a retired physicist formerly affiliated to the Research Center of ENEA at Frascati (Italy), where he has developed predominantly his research activities, as well as with the Universities of Berkeley and Salt Lake City, is a leading figure in the study of optical properties of color centers in inorganic and organic solid state. The most important techniques have been used to analyse absorption, emission, lifetimes of the excited levels and dynamical processes of luminescence properties under various conditions. For more than a half-century, Dr. Giuseppe Baldacchini has contributed greatly to the Science of Materials. He is widely known and respected as an innovator and educator, a scientist with an enormous breadth of interest and depth of insight. I had the privilege to meet him almost every year, since 1983, at the International School of Atomic and Molecular Spectroscopy at Erice (Sicily, Italy) headed by Prof. Di Bartolo, and then having attended each of his lectures I am the witness of all his efforts in the knowledge of Alq3 organometallic luminescence, the purpose of this book. His own teaching skills and his capacity to convince the audience of the School could benefit from the same approach by reading this book on the evaluation of the complex optical properties of Alq3 through the photoluminescence method. Finally, we can say that the genesis of the 'Four components model' adopted in all the chapters of this book, allowing to reach some valuable conclusion, is a good example of the profound insight needed by luminescence researchers and should be known by the greatest number of us." --Societa Italiana De Fisica (Italian Physical Society)

"This book is a unique reference book on Alq3 materials. It includes lists of references for further study and loads of graphical data showing the properties obtained for Alq3 under various conditions. Those readers interested in OLED materials, specifically Alq3 OLED materials, would enjoy this book. " --IEEE
