What elements are found in phosphor powders of fluorescent lamps?
Based on the XRF analysis results, waste phosphor powders of fluorescent lamps contain rare-earth elements such as Y, Eu, La, Ce, Pr, and Tb at ~30% of the total weight, and other elements are mainly Ca and Sr, and a variety of metals such as Al, Ti, V, Fe, and Zn as shown in Fig. 12.3B.
What phosphors are used in fluorescent lamps?
The discovery in of calcium halophosphate phosphors, with emission over a broad band of visible wavelengths, was a major breakthrough in the industry. These phosphors are still used in fluorescent lamps, since they are relatively inexpensive and provide CRI in the range 51–76.
What is luminophore used for?
This luminophore has very high scintillation efficiency, but is available usually as a polycrystalline powder. As a result, its use is limited to thin screens primarily meant for alpha-particle or neutron detection.
