Talk Title: uminescence of Oxides for Sensors and New Laser Gain Materials
Series: Lyman L. Handy Colloquium Series
Abstract: Luminescence is one of the most distinctive properties of a material and consequently continues to attract both artistic and scientific interest. And, although the underlying physics has been well established for many years it remains difficult to predict in detail the luminescence spectra of luminescent ions doped in complex oxide hosts and its dependence on temperature, doping concentration and strain. Consequently, the subject provides a wonderful play ground for those of us interested in tailoring, for instance, new phosphor materials, sensors or adding multi‐functionality to existing materials. In my talk I will describe two quite different examples of exploring doping schemes, one to create a luminescence sensor for sensing temperature (and damage) in thermal barrier coatings and the other for identifying a new class of high‐power laser gain material. These exemplify the necessity of combining an understanding of the essential physics with knowledge of crystal chemistry and materials processing, the synthesis of scientific knowledge required in developing new materials today.
