Volume 61 of the Handbook on the Physics and Chemistry of Rare Earths (Including Actinides) features three chapters that describe luminescence enhancement in perovskite–lanthanide composites, the role of lanthanide ions in optical sensing and the Internet of Things (IoT), and the design of macrocyclic ligands for application of lanthanide complexes in bioanalysis and bioimaging. Chapter 323 illustrates the efforts made toward improving photon management in lanthanide–perovskite hybrid materials for developing high-level optoelectronic applications including luminescent solar concentrators, solar cells, and light-emitting diodes (LEDs). Chapter 324 emphasizes the key role played by optical sensors coupled to smartphones in the establishment of the IoT, particularly with respect to providing trustable healthcare services. Chapter 325 analyzes the structural features required for designing thermodynamically stable and kinetically inert lanthanide complexes to be used in various biological and biomedical applications. Lanthanide luminescence has several advantages over that of other materials, in particular the high color purity of their emission and, in the case of inorganic phosphors, a welcome photostability. Considering the diversity of ions in the 4f element series, each emitting specific and easily recognizable sharp lines, these ions can be turned into useful and efficient light-converting devices, thanks to downshifting, downconversion, and upconversion processes.

However, their absorption cross section is extremely small that it is

difficult to engineer highly bright lanthanide phosphors unless a large excitation

power is provided. To circumvent this bottleneck, luminescent material

designers take advantage of nonradiative resonance energy transfer between

a matrix and the emissive ions. In Chapter 323, the authors describe the fruitful

interactions between lead perovskites and lanthanide ions. Doping the latter

into the former enables efficient excitations
