The attractive features of lanthanide-doped upconversion luminescence (UCL), such as high
photostability, nonphotobleaching or photoblinking, and large anti-Stokes shift, have shown …

Lanthanide pairs, which can upconvert low energy photons into higher energy photons, are
promising for efficient upconversion emission. A typical system with Yb3+ as a sensitizer can …

The trivalent europium ion (Eu 3+) is well known for its strong luminescence in the red
spectral region, but this ion is also interesting from a theoretical point of view. Due to the …

NaYF4: Yb: Er nanoparticles (UCNP) were synthesized under mild experimental conditions
to obtain a pure cubic lattice. Upon annealing at different temperatures up to Tan= 700° C …

Lanthanide‐doped upconversion nanoparticles (UCNPs) are an emerging class of
luminescent materials that emit UV or visible light under near infra‐red (NIR) excitations …

The temperature-dependent upconversion luminescence of NaYF4: Yb: Er nanoparticles
(UCNP) containing different contents of Gd3+ as additional dopant was characterized. The …

Lanthanide-based luminescent anti-counterfeiting materials are widely used in various kinds
of products. However, the emission color of traditional lanthanide-based luminescent …

Abstract Trivalent europium ions (Eu 3+) activated inorganic materials, known as one of the
most important red-emitting phosphors, are emerging as an attractive class of luminescent …

Er3+/Eu3+/Yb3+: NaZnPO4 nanophosphors synthesized using the co-precipitation
technique are structurally and optically characterized. The effect of the Eu3+ ion …

Potassium calcium mixed borate, KCaBO3: Er3+, phosphors with varied Yb3+
concentrations were synthesized by solid-state reaction and studied for the first time. The …
