The enthusiasm for research on lanthanide‐doped upconversion nanoparticles is driven by
both a fundamental interest in the optical properties of lanthanides embedded in different …

808 nm‐light‐excited lanthanide (Ln3+)‐doped nanoparticles (LnNPs) hold great promise
for a wide range of applications, including bioimaging diagnosis and anticancer therapy …

Photon upconversion of near-infrared photons is a promising way to overcome the Shockley–
Queisser efficiency limit of 32% of a single-junction solar cell. However, the practical …

In this Letter we report the plasmon-enhanced upconversion in single NaYF4 nanocrystals
codoped with Yb3+/Er3+. Single nanocrystals and gold nanospheres are investigated and …

In any given matrix control over the final particle size distribution requires a constitutive
understanding of the mechanisms and kinetics of the particle evolution. In this contribution …

This article reports on the visible upconversion and temperature sensing behaviour of Er 3+–
Yb 3+ doped/codoped TeO 2–WO 3 glasses prepared by a melting and quenching method …

An engineered plasmonic gold surface, specifically designed to couple with 980 nm
radiation, is shown to enhance near-infrared-to-visible upconversion luminescence from a …

Transparent Ag and Eu^ 3+ co-doped oxyfluoride glasses with composition 50SiO_2-
20Al_2O_3-30CaF_2 were prepared by melt-quenching technique. The structural and …

Particles of sizes between 1 and 100 nm show fascinating properties with unusual
characteristics that lead to the formation of unique properties in nanosystems, which are not …

The upconversion (UC) of the rare earth doped glass-ceramics has been extensively
investigated due to their potential applications in many fields, such as color display, high …
