متن کاملCathodoluminescent Display Phosphors
The past several years rendered a resurgence of interest in phosphors for lowvoltage flat panel displays utilizing cathodoluminescence (CL). A major selection criterion for these phosphors is CL efficiency. The objective is to maximize the efilciency at low voltages. This work focuses on understanding the materials properties that influence CL efficiency below 1 kV. Existing high-voltage CL eff...
متن کاملStorage Phosphors for Medical Imaging
Computed radiography (CR) uses storage phosphor imaging plates for digital imaging. Absorbed X-ray energy is stored in crystal defects. In read-out the energy is set free as blue photons upon optical stimulation. In the 35 years of CR history, several storage phosphor families were investigated and developed. An explanation is given as to why some materials made it to the commercial stage, whil...
متن کاملTransient measurements using thermographic phosphors.
The decay of thermographic phosphors has been used to measure temperature in a wide variety of applications. Because measurements of a single temperature are obtained from intensity decay in time, the use of phosphors is predicated on the fact that the temperature does not change during the decay. This may not be valid in some engineering applications. A new model for phosphor data reduction de...
