Rare Earth Upconversion nanoparticles (UCNPs) are a type of material that emits high-
energy photons by absorbing two or more low-energy photons caused by the anti-stokes …

Light-based therapies and diagnoses including photodynamic therapy (PDT) have been
used in many fields of medicine, including the treatment of non-oncological diseases and …

Luminescent materials have been widely utilized for anti-counterfeiting applications due to
their good feasibility for tunable optical properties. Herein, an anti-counterfeiting strategy …

Upconverting nanoparticles has a significant potential to enhance solar cell efficiency as a
“spectral converter”. Here, we report a phase pure, cubic, upconverting BaGdF5: Er/Yb …

Trivalent erbium and ytterbium embedded in Lu 3 Sc 2 Ga 3 O 12 nanocrystals in the garnet
phase were synthesised employing the citrate sol-gel method. The crystalline phase and …

Abstract Ho 3+ and Yb 3+ co-doped La 7 P 3 O 18 up-conversion phosphors were prepared
by a high-temperature solid-state process. XRD results reveal that the samples are mixtures …

In the pursuit of efficient red-emitting phosphors, a series of red-emitting Na 7 Mg 13 La (PO
4) 12: Eu 3+ phosphors was prepared using a high-temperature solid-state synthesis …

The blue-emitting KBaYSi 2 O 7: Bi 3+ phosphor was prepared via the high-temperature
solid-phase method, and the structural Si 4+ was partially substituted by Al 3+ and Ge 4+ to …
