At the Phosphor Global Summit there is a unique mix between experts from academics involved in luminescent materials research and experts from industry.
Falmouth, ME (PRWEB) February 16, 2011
As a lead up to IntertechPira’s 9th annual Phosphors Global Summit conference, taking place March 22-24 at the Westin Riverwalk San Antonio in San Antonio, Texas, conference co-chair Dr. Thomas Jüstel of the University of Applied Sciences Muenster recently interviewed his fellow conference speaker Professor Andries Meijerink, University Utrecht, on some of the hot topics in the phosphors industry. Below is a partial transcript of the interview.
Dr. Thomas Jüstel: Do you see areas in lighting and imaging to replace rare earth phosphors by transition metal phosphors in order to overcome the emerging shortage of rare earth metals?
Prof. Andries Meijerink: The shortage of lanthanides is not because rare earths are rare but is caused by a strategic reduction in export by China. The increasing importance of rare earths in emerging green technologies — such as magnets, batteries, catalysts and energy saving light sources — combined with the dominant position of China in the market will cause a shortage that will impact the near future. For the Tb-rich green phosphor in (compact) fluorescent lamps, transition metal ion alternatives may give a significant price reduction. I expect research in this direction to increase. For the white light LEDs the impact is less dramatic, as the amounts of rare earths used is small and the main elements used, Ce and Eu, are not as strongly affected as, for example, Nd and Tb. In the field of medical imaging not only transition metals but also s2 ions are promising candidates to replace lanthanides if the shortage becomes serious. For the farther future it is important to monitor how the market develops and to see how the long term demand can be met by a more balanced supply from RE-mines (re-)opening in countries such as the USA, Canada and Australia.
Dr. Thomas Jüstel: What sets the Phosphor Global Summit apart from other conferences in the field of luminescent materials?
Prof. Andries Meijerink: At the Phosphor Global Summit there is a unique mix between experts from academics involved in luminescent materials research and experts from industry. No other conference I visit succeeds in attracting the key players from both sides in one meeting. The meeting is compact at two days and has a strong focus on new developments in luminescent materials. For me as an academic it is unusual to have a few talks discuss the properties of an undisclosed compound X, but it gives me better insight in the issues and challenges faced by the industry in developing the next generation of luminescent materials.
Phosphor Global Summit 2011 is co-chaired by Dr. Thomas Jüstel as well as Kathryn Conway, principal, LED Consulting. The conference will feature more than 20 presentations as well as a full day of pre-conference seminars, including “Fundamental Concepts of Luminescence Spectroscopy/Basics of White LED Phosphors,” which will be co-presented by Professor Andries Meijerink.
