Special Issue on Rare Earth Luminescent Materials
Owing to the unique electronic configuration of rare earth ions, their luminescent materials exhibit very attractive optical properties in broad spectral region, such as sharp-band emissions, tunable excitation/emission, large Stokes/anti-Stokes shifts, long luminescent lifetimes, and excellent photostability. Rare earth luminescent materials are thus recognized as the treasure house of the optical materials. Over the past 50 years, the rare earth luminescent material family has developed rapidly, and their applications have been expanded from traditional lighting, display, lasing and waveguiding to many emerging fields, such as information technology, energy conservation, sensor and testing, biomedicine, and so on.
This special issue covers a series of cutting-edge works on exploring novel rare earth luminescent materials, including lanthanide ions doped phosphors, persistent luminescent materials, lanthanide ions doped upconversion materials, and rare earth relevant perovskite materials, and their applications in lighting, display, information storage, sensing, and bioimaging as well as therapy.
