Frequency upconversion nanoparticles (UCNPs) are inorganic nanocrystals capable to up-convert incident photons of the near-infrared electromagnetic spectrum (NIR) into higher energy photons. These photons are re-emitted in the range of the visible (Vis) and even ultraviolet (UV) light. The frequency upconversion process (UC) is realized with nanocrystals doped with trivalent lanthanoid ions (Ln(III)). The Ln(III) ions provide the electronic (excited) states forming a ladder-like electronic structure for the Ln(III) electrons in the nanocrystals. The absorption of at least two low energy photons by the nanoparticle and the subsequent energy transfer to one Ln(III) ion leads to the promotion of one Ln(III) electron into higher excited electronic states. One high energy photon will be emitted during the radiative relaxation of the electron in the excited state back into the electronic ground state of the Ln(III) ion. The excited state electron is the result of the previous absorption of at least two low energy photons. [...].

Download An Investigation Into Tunable Emission with Multidopant Upconverting Nanoparticles Using Core-shell Structures Book in PDF, ePub and Kindle
Upconverting nanoparticles (UCNPs) are trivalent lanthanide doped inorganic nanocrystals which undergo sequential multiphoton absorption, converting near infrared radiation to emissions in the ultraviolet and visible regions. The unique optical properties of UCNPs make them attractive for the development of tools for bioanalysis, theranostics, and sensor technology. These properties include the characteristic narrow emission peaks resulting from the choice of host lattice material, dopants ratios/type, and core-shell design. One of the challenges in designing UCNPs for biomedical and theranostics applications is co-doping the material with multiple activators to ameliorate the decrease of luminescence caused by quenching mechanisms. Herein, the design of multidopant UCNPs will be explored using a multilayer shell design. The intention is investigation of energy migration mechanisms within the material to learn to control luminescence properties such as the selection of multiple emission wavelengths and the relative intensities at such wavelengths.

Download Upconverting Nanomaterials Book in PDF, ePub and Kindle
Upconverting Nanomaterials: Perspectives, Synthesis, and Applications serves as a powerful instrument that explores cutting-edge research knowledge on the topic of upconverting nanosystems, while simultaneously providing the necessary fundamental background for nonspecialist readers. The various aspects of upconverting materials are approached both from a theoretical point of view, particularly upconverting phenomenon, and a practical one. By presenting synthetic strategies, functionalization, production of core shell structures and nanocomposites, this book supplies PhD students, researchers, and scientists with a wealth of ideas they can apply to different fields of research. Thirty-five renowned scientists from around the world have collaborated to produce 11 chapters that help to "make a voyage" through the most important aspects of UPNPs, including syntheses, mechanism, functionalization, and applications.
