Download Mechanisms Affecting Emission in Rare-earth-activated Phosphors Book in PDF, ePub and Kindle
The relatively poor efficiency of phosphor materials in cathodoluminescence with low accelerating voltages is a major concern in the design of field emission flat panel displays operated below 5 kV. The authors research on rare-earth-activated phosphors indicates that mechanisms involving interactions of excited activators have a significant impact on phosphor efficiency. Persistence measurements in photoluminescence (PL) and cathodoluminescence (CL) show significant deviations from the sequential relaxation model. This model assumes that higher excited manifolds in an activator de-excite primarily by phonon-mediated sequential relaxation to lower energy manifolds in the same activator ion. In addition to sequential relaxation, there appears to be strong coupling between activators, which results in energy transfer interactions. Some of these interactions negatively impact phosphor efficiency by nonradiatively de-exciting activators. Increasing activator concentration enhances these interactions. The net effect is a significant degradation in phosphor efficiency at useful activator concentrations, which is exaggerated when low-energy electron beams are used to excite the emission.

Download Polymers, Phosphors, and Voltaics for Radioisotope Microbatteries Book in PDF, ePub and Kindle
As the first book written solely on the subject of nuclear batteries and their potential to revolutionize the electronics industry, this text will appeal to a broad audience, from engineers to energy policy makers. This collection of contributions from leading U.S. and Russian nuclear researchers contains diverse discussions of the problems of using radioactive material for microelectronic power needs, and it guides readers to future research in the area of long-life, high energy-density batteries. It describes the state of interdisciplinary research in radiochemistry, tritium storage, semiconductor fabrication, integration into MEMS and other electronic devices, and much more.
