Special Issue Information

Dear Colleagues,

The last twenty years of research on materials doped with lanthanide ions have been largely devoted to the development of their nanostructured counterparts. Thanks to this, the unique luminescence of lanthanide ions has been used in new applications, such as those related to the development of nanomedicine. The miniaturization of devices, attempts to introduce nanoparticles into the structure of living organisms, and the search for more and more advanced spectroscopic properties have also resulted in the development of synthesis methods. Consequently, the luminescence performance in nanostructured systems has improved, and it has become possible to use the unique properties of nanomaterials containing lanthanide ions in temperature or pressure sensors as well as in analytical applications in the detection of ions and biomolecules. In particular, the phenomenon of up-conversion is being intensively studied due to potential applications in theranostics and in the conversion of solar energy in solar panels.

To reflect the current state of the research on nanomaterials activated by lanthanide ions, we are inviting you to contribute to this Special Issue by publishing a research or review article.

The synthesis of upconverting nanoparticles (NPs) is crucial for their spectroscopic properties and further applications. Reducing the size of materials to nano-dimensions usually decreases emission intensity. Therefore, scientists around the world are trying to improve the methods of obtaining NPs to approach levels of emission intensity similar to their bulk counterparts. In this article, the effects of stearic acid on the synthesis of core@shell β-NaYF4: 18%Yb3+, 2%Er3+@β-NaYF4 upconverting NPs were thoroughly investigated and presented. Using a mixture of stearic acid (SA) with oleic acid and 1-octadecene as components of the reaction medium leads to the obtaining of monodispersed NPs with enhanced emission intensity when irradiated with 975 nm laser wavelength, as compared with NPs prepared analogously but without SA. This article also reports how the addition of SA influences the structural properties of core@shell NPs and reaction time. The presence of SA in the reaction medium accelerates the growth of NPs in comparison with the analogic reaction but without SA. In addition, transmission electron microscopy studies reveal an additional effect of the presence of SA on the surface of NPs, which is to cause their self-organization due to steric effects.

Lanthanide-activated alkaline earth aluminate phosphors are excellent luminescent materials that are designed to overcome the limitations of conventional sulfide-based phosphors. The increasing research attention on these phosphors over the past decade has led to a drastic improvement in their phosphorescence efficiencies and resulted in a wide variety of phosphorescence colors, which can facilitate applications in various areas. This review article discusses the development of lanthanide-activated alkaline earth aluminate phosphors with a focus on the various synthesis methods, persistent luminescence mechanisms, activator and coactivator effects, and the effects of compositions. Particular attention has been devoted to alkaline earth aluminate phosphors that are extensively used, such as strontium-, calcium-, and barium-based aluminates. The role of lanthanide ions as activators and coactivators in phosphorescence emissions was also emphasized. Finally, we address recent techniques involving nanomaterial engineering that have also produced lanthanide-activated alkaline earth aluminate phosphors with long-persistent luminescence.
